Color photographic apparatus

摘要

A color electrophotographic apparatus eliminates necessity of mechanism for urging the developer from the front side. The developer is placed away from a photo conductor. On both sides of the developer, mutually cooperated gears are provided. One of the gear meshes with a drive gear with a clutch for driving the developer. The other gear is meshed with a brake gear coupled with a brake mechanism whose brake function can be turned On and OFF by an electric signal. The drive gear is arranged to urge the developer onto the photo conductor by rotation thereof. When the gear of the developer rotates, the brake gear is arranged at a position to urge the developer onto the photo conductor. The torque to start slippage of the brake is set at a value to be greater than a force of a spring pushing back the developer.
