ABSTRACT:
An electrophotographic photoreceptor having excellent dark resistance is disclosed, which comprises a photoconductive layer and a surface layer formed successively on a conductive substrate, wherein the photoconductive layer mainly comprises hydrogen-containing amorphous silicon, and the surface layer comprises amorphous carbon which contains not more than 50 atomic percent of hydrogen. The surface layer contains phosphorous or boron as a dopant and/or comprises two sublayers where the sublayer has a lower hydrogen content than the lower sublayer.
