ABSTRACT:
A color image forming apparatus provided with a developing device for developing latent images formed on a latent image bearing member. The developing device includes a rotary assembly for carrying a plurality of developing units so that the developing units revolve by the rotation of the rotary assembly, so as to dispose a desired or necessary one of the developing units at a developing station where the latent image on the latent image bearing member is developed. Each of the developing units is provided with an element or elements to be driven, such as a developing roller or the like. A single driving mechanism is provided in the image forming apparatus, which driving mechanism can drive any of the developing units when it is placed at the developing position. For this purpose, the driving mechanism is engageable with that one of the developing units revolvable on the rotary assembly which is located at the developing station to develop the latent image on the latent image bearing member, so that the driving force is transmitted to the element of the unit requiring the driving force.
