ABSTRACT:
An image-forming apparatus, for example, a color electrophotographic apparatus, includes two development stations. Each development station includes an applicator with a rotatable component which moves developer into toner-applying relation with an electostatic image carried on an image member. The two rotatable components are driven by a single motor selectively according to whether the motor is driven in a forward or reverse direction. A one-way clutch in the drive train of each rotary component prevents rotation of that component when the other station's rotary component is being driven.
