ABSTRACT:
A charging process, an exposure process, and a development process are performed to form a toner image on a photosensitive member for each of a plurality of different colors. The toner images for the respective colors form a composite color image. The composite color image is transferred to a sheet. A potential of toner on the photosensitive member is varied before the development process for a final color is performed. The colors may be yellow, magenta, and cyan respectively.
