An image forming apparatus includes a development device including a development roller and a driving force receiving member, a movable member configured to move the development device between a development position and a retracting position, a first driving force transmission member configured to transmit a driving force to the movable member, a second driving force transmission member configured to engage with the driving force receiving member and transmit the driving force to the driving force receiving member, and a controller configured to perform drive control for the first driving force transmission member based on a temperature detected by a sensor. If α1 represents acceleration of the development device in a case where the temperature is T1 and the driving force receiving member disengages from the second driving force transmission member and α2 represents acceleration of the development device in a case where the temperature is T2 and the driving force receiving member disengages from the second driving force transmission member, the controller performs the drive control for the first driving force transmission member so as to satisfy a relationship α1≦α2 when T1≦T2.
