Abstract
In an image forming apparatus, revolver or rotary developing unit and a revolver motor include a revolver gear and a motor gear, respectively. While a reaction acts from the revolver gear on the motor gear, a bracket bears the side surface or surfaces of the revolver motor in order to prevent the teeth of the motor bear and those of the revolver gear from skipping each other. The reaction acting on a motor mount is scattered in order to protect the characteristic of the motor mount from deterioration.
