Abstract

PURPOSE: To obtain the captioned photoreceptor with which chromatic color A or B is sufficiently identifiable when the original of chromatic color A or B other than black is subjected to white and black copying by laminating and using two layers of photoconductive layers having the specific spectral sensitivities.
CONSTITUTION: The 1st photoconductive layer which is sensitive to chromatic color light A under positive (or negative) charging and the 2nd photosensitive layer which allows the transmission of the chromatic color light A and is sensitive to chromatic color light B under positive or negative (i.e., same polarity with that of the 1st photoconductive layer) are subsequently laminated on a conductive substrate, whereby the composite photoreceptor for electrophotography is obtained.
