Abstract
A rotary developing device includes a developing unit having a plurality of developing chambers arranged around an axis of rotation of the developing unit and each having a developer agitating mechanism thereinside wherein the rotary developing device is rotatable about the axis to locate any one of the plurality of developing chambers at a developing position where an image carrier is located. The device includes a drive inputting device located in proximity with the axis of the rotation for inputting a driving force to the agitating mechanism of one of the plurality of developing chambers which is located at the developing position. A drive transmitting mechanism is provided which transmits at a developing units side, a driving force to at least one of the plurality of developing chambers not located at the developing position.
