Abstract
A rotary developing device having a cylindrical rotary developing unit, and a plurality of development members mounted around the periphery of the rotary developing unit. The rotary developing unit is driven to bring one of the development members to the developing position facing a photoreceptor and subsequently the transmission of the driving power to the development member is conducted. In the rotary developing device, the driving direction of the development members at a driving power transmitting section is set to be the same as the driving direction of the rotary developing unit and a simple additional structure employing an electromagnetic clutch or a one-way clutch is applied to the driving power transmitting section, thereby avoiding a collision of tooth tops between gears, damping the impact generated by a collision, and reducing vibration and damage of tooth tops. Therefore, the production of image defects due to registration error are prevented.
