Method and apparatus for colour electrophotography.

摘要

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. Second color toner image forming processes are effected subsequently to first color toner image forming processes. The first color charging process charges the photosensitive member to a first potential. The second color charging process charges the photosensitive member to a second potential. The second potential is set equal to or lower than the first potential. The composite color image is transferred to a sheet.
