Abstract
PURPOSE: To obtain the captioned photoreceptor which permits ordinary black and white copying and two-color copying through one exposure 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 both positive and negative charging and the 2nd photosensitive layer which allows the transmission of the chromatic color liqht A and is sensitive to chromatic color light B only under positive (or negative) charging are subsequently laminated on a conductive substrate and the ratio between the sensitivity of the 2nd photoconductive layer and the sensitivity of the 1st photoconductive layer which makes the 2nd photoconductive layer as its filter is made 1W20, whereby the composite photoreceptor for electrophotography is obtained.
