ABSTRACT:
An electrophotographic photoreceptor is constituted by forming a barrier layer, a photoconductive layer including a charge-generating layer and a charge-transportation layer, and a surface layer on an aluminum substrate drum, in the order stated. The charge-generating layer of this electrophotographic photoreceptor has a superlattice structure of a heterojunction constituted by alternately stacking thin a-Si:H layers and thin .mu.c-SiC:H layers. In this superlattice structure, the optical bandgaps of the respective layers differ from each other, a-Si:H serves as a potential barrier, and .mu.c-SiC:H serves as a potential well. When light is radiated on the charge-generating layer, a large number of photocarriers are generated. The photocarriers having one polarity pass through the barrier by way of a tunneling effect, and propagate in the charge-generating layer. In addition, the charge-transporting layer is formed by a-Si:H or .mu.c-Si:H, and hence more easily enables allows photocarriers generated in the charge-generating layer to reach the conductive substrate.
