Abstract

An image-forming apparatus particularly usable in making multicolor toner images includes toning stations in pairs. First and second toning stations each have a toner applicator. A spacing roller or disk is mounted at each end of each applicator. Because the toning unit includes two stations and two applicators, the four disks can be used to accurately position the applicators with respect to an image surface such as a photoconductive drum.
