Abstract
A color electrophotographic image forming apparatus includes a rotatable supporting member to support a number V of developing devices. A drive transmission mechanism is provided in which each time one of the number V of engaging portions on a rotary member is disengaged from and engaged with an electric actuator, a gear portion of a rotatable supporting member gear which is rotated in synchronism with the rotary member is engaged with a driving member such that the rotatable supporting member is rotated by an angle W which satisfies (360°/V) and stopped.
