ABSTRACT:
An electrophotographic photoreceptor constituted by a conductive substrate, and a photoconductive layer, provided on the conductive substrate, for generating photocarriers upon radiation of light is disclosed. The photoconductive layer has a charge-generating layer and a charge-retaining layer. The charge-generating layer comprises a semiconductor containing silicon as a major constituent. The charge-retaining layer comprises a multilayered body constituted by alternately stacking first amorphous semiconductor layers containing silicon as a major constituent and second amorphous semiconductor layers containing silicon as a major constituent and at least one element selected from the group consisting of carbon, oxygen, and nitrogen. A concentration of the element is changed in a direction of thickness of the charge-retaining layer for each second amorphous semiconductor layer.
