Abstract

PURPOSE: To let two color originals to be copied distinctly by one copying process by subsequently laminating the first photoconductive layer which has no sensitivity to light of a color A and the second photoconductive layer having sensitivity to a color A on a conductive substrate at the time of forming the electrophotographic photoreceptor.
CONSTITUTION: The first photoconductive layer which does not have sensitivity to light of a color A and has the potential holding capability capable of making sufficient contribution of the surface potential formation of the photoreceptor when negative or positive corona charging is applied to the surface of the formed photoreceptor. Next, the second photoconductive layer which is composed of the layer containing the eutectic complex of pyrylium salt, thiapyrylium salt, selenapyrylium salt derivatives and the electrically insulating polymer having alkylidene diallylene portions and the transparent layer which has capability of transporting hole and electron, has sensitivity to the light of the color A and has the similar potential holding capacity to that of the first photoconductive layer is laminated.
