Abstract

PURPOSE: To form the captioned photoreceptor by which always distinct images are obtainable even in single color copying and two color copying by selectively combining electrophotographic members which are sensitive to A-color light and photoconductive sheets which are sensitive to light other than A-color light.
CONSTITUTION: The electrophotographic member (S2 member) provided with the photoconductive layer 12 which is sensitive to A-color light and capable of forming the surface potential opposite from the changing polarity of a photoconductive sheet (S1 member) 14 and the photoconductive sheet (S1 member) 14 of about 3W100μ in thickness comprising dispersing colored photoconductive particles in binders are combined on a conductive substrate 11 to provide the electrophotographic photoreceptor. In the case of performing black and white copying, the S1 member of the abovementioned photoreceptor is not used and only the S2 member is used as a photoreceptor and copying is done by an ordinary Carlson method and in the case of performing two color copying, electrophotographic copying is performed by contacting and placing the S1 member on the photoconductive layer of the S2 member.
