現像装置。[Scope of Claim for Utility Model Registration] A multicolor developing device in which a plurality of developing units are selectively brought close to a photosensitive member by rotation to visualize an electrostatic latent image on the photosensitive member, wherein the developing units are integrated with each other. Each developing unit is horizontally supported between a pair of side plates, one of which is a gear, and the rotational force of the drive means is transmitted through one of the side plates, which is a gear. A multi-color developing device comprising: sensor means for detecting the passage of the teeth of the one side plate during rotation; and the drive means is controlled based on a value detected by the sensor means.
