Abstract:
1. An image forming apparatus comprising: a development device including a development roller carrying a developer to develop an electrostatic image and a driving force receiving member configured to receive a driving force to rotate the development roller; a movable member configured to hold the development device and move the development device between a development position where the development device performs development and a retracting position where the development device separates from the development position; a first driving force transmission member configured to transmit a driving force to the movable member to move the development device; 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 in a state where the development device is located at the development position; a sensor configured to detect an internal body temperature of the image forming apparatus; and a controller configured to perform drive control for the first driving force transmission member based on the temperature detected by the sensor; wherein if α the controller performs the drive control for the first driving force transmission member so as to satisfy a relationship α
