Abstract
In an image forming apparatus including a rotary member () to which a plurality of developing cartridges (B, Y, M, C) () are detachably mountable, a user can rotate the rotary member with an easy operation to access the plurality of developing cartridges. A pivotable unit () is contactable and separable from a driving train for the rotary member (). By applying a certain braking force to a pivotal gear (), the pivotal gear () is moved to a position at which the pivotal gear () is held in contact with the driving train by a user's operational force. In association with the contact movement of the pivotable unit (), a solenoid () performing a positional control of the rotary member () is released.
