摘要： 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.

摘要： An electrophotographic photoreceptor comprising a photoconductive layer, a first surface layer and a second surface layer formed in sequence on a support, said photoconductive layer being substantially composed of amorphous silicon, and each of said first and second surface layers being substantially composed of nitrogen-doped amorphous silicon, the concentration of nitrogen atoms in the second surface layer being higher than that in the first surface layer. The photoconductive layer is doped with atoms of an element of group III, or in at least a part of the photoconductive layer doped with germanium atoms in place of the element of group III.
