APPAREIL D'ELECTROPHOTOGRAPHIE EN COULEURS

摘要

Color electrophotographic apparatus comprises a plurality of operation stations each of which has a charging section, an optical image exposure section and a developing section. Two sets of endless belts travel between the plurality of operation stations and convey a flexible electrophotographic material. The endless belts contact only the end or edge portions of the electrophotographic material. An optical system is provided wherein the optical axis for exposing the electrophotographic material is maintained in the same position in all the optical image exposure sections, the surface of the photoconductive insulating layer is perpendicular to the optical axis, and the optical images formed on the insulating layer are equal to each other in size during all exposures.
