Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the fiscal year ended October 31, 2019, the Fund’s portfolio turnover rate was 129% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement for the contractual period above and the Total Annual Fund Operating Expenses thereafter. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets, including any borrowings for investment purposes, in securities of “mid cap” companies, and in derivatives and other instruments that have economic characteristics similar to such securities. A company’s “market capitalization” is the value of its outstanding common stock. The Fund considers mid cap companies to be those having a market capitalization in the range of the Russell Midcap® Value Index, a measure of the mid cap value market. The capitalization range of the index is subject to change at any time due to market activity or changes in the composition of the index. The range of the Russell Midcap® Value Index generally widens over time and is reconstituted annually to preserve its mid cap characteristics. The Fund measures a company’s capitalization at the time the Fund buys a security and is not required to sell a security if the company’s capitalization moves outside of the Fund’s capitalization definition. The Fund may also invest in small cap companies, and up to 5% of its total assets in securities of unseasoned companies. The Fund primarily invests in U.S. companies but may also purchase securities of issuers in any country, including developing and emerging market countries. While the Fund has no limits on the percentage of its assets it can invest in foreign securities, normally it does not expect to invest substantial amounts of its assets in foreign securities and generally limits investments in emerging markets to not more than 5% of its total assets. The Fund emphasizes securities that the portfolio manager believes are undervalued. In selecting investments for the Fund, the portfolio manager looks for stocks of mid-cap companies that he believes have been undervalued by the market. A security may be undervalued because the market is not aware of the issuer’s intrinsic value, does not yet recognize its future potential, or the issuer may be temporarily out of favor. The Fund seeks to realize gains in the prices of those securities when other investors recognize their real or prospective worth. The portfolio manager uses a “bottom up” approach to select securities one at a time before considering industry trends. Those companies may have a low ratio of their stock price to earnings, for example. The portfolio manager also analyzes factors such as a company’s book value, sales, earnings, growth potential and cash flows. After considering these criteria, the portfolio manager may also look at broader industry and economic trends that could affect the growth potential of particular mid-cap stocks. The portfolio manager currently focuses on companies with the following characteristics, which may vary in particular cases and may change over time: Favorable supply/demand conditions for key products Development of new products or businesses Quality of management Competitive position in the marketplace Effective allocation of capital The Fund may sell securities that the portfolio manager believes no longer meet the above criteria, but is not required to do so. In attempting to meet its investment objective or to manage subscription and redemption requests, the Fund engages in active and frequent trading of portfolio securities.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Risks of Investing in Stocks. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets. The prices of individual stocks generally do not all move in the same direction at the same time. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities. Risks of Mid-Cap Companies. Mid-cap companies generally involve greater risk of loss than larger companies. The prices of securities issued by mid-cap companies may be more volatile and their securities may be less liquid and more difficult to sell than those of larger companies. They may have less established markets, fewer customers and product lines, less management depth and more limited access to financial resources. Mid-cap companies may not pay dividends for some time, if at all. Risks of Value Investing. Value investing entails the risk that if the market does not recognize that a selected security is undervalued, the prices of that security might not appreciate as anticipated. A value approach could also result in fewer investments that increase rapidly during times of market gains and could cause a fund to underperform funds that use a growth or non-value approach to investing. Value investing has gone in and out of favor during past market cycles and when value investing is out of favor or when markets are unstable, the securities of “value” companies may underperform the securities of “growth” companies. Industry and Sector Focus. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry. Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight. Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective. Active Trading Risk. Active trading portfolio securities may result in added expenses, a lower return and increased tax liability.
Risk Lose Money [Text]	rr_RiskLoseMoney	As with any mutual fund investment, loss of money is a risk of investing.
Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Mid Cap Value Fund (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31. The performance table compares the predecessor fund’s and the Fund’s performance to that of a broad-based securities market benchmark. For more information on the benchmark used see the “Benchmark Descriptions” section of the prospectus. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C, Class R and Class Y shares of the predecessor fund. Class R6 shares’ returns shown for periods ending on or prior to May 24, 2019 are those of the Class I shares of the predecessor fund. Class A, Class C, Class R and Class Y shares of the predecessor fund were reorganized into Class A, Class C, Class R and Class Y shares, respectively, of the Fund after the close of business on May 24, 2019. Class I shares of the predecessor fund were reorganized into Class R6 shares of the Fund after the close of business on May 24, 2019. Class A, Class C, Class R, Class Y and Class R6 shares’ returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund’s applicable sales charge. Class R5 shares of the Fund have less than a calendar year of performance; therefore, the returns shown are those of the Fund’s and predecessor fund’s Class A shares. Although the Class R5 shares are invested in the same portfolio of securities, Class R5 shares’ returns of the Fund will be different from Class A returns of the Fund and predecessor fund as they have different expenses. Updated performance information is available on the Fund’s website at www.invesco.com/us.
