摘要:
An electrophotographic image-forming member which comprises a substrate for electrophotography and a light receiving layer being disposed on said substrate, said light receiving layer comprising a photoconductive layer formed of a non-single-crystal silicon carbide film containing silicon atoms as a matrix, carbon atoms in an amount of 5 to 15 atomic % and hydrogen atoms in an amount of 1 to 10 atomic %, containing graphite structure domains in a proportion of 1% or less per unit volume and having an intensity ratio of 0.01 to 0.05 between the C--H bond stretching mode and the Si--H bond stretching mode in an infrared adsorption spectrum.The light receiving layer may further comprise a charge injection inhibition layer or/and a surface layer.The electrophotographic image-forming member can be used in a high-speed continuous electrophotographic copying systems using a coherent light laser beam as the light source without accompaniment of the problems which are found on conventional amorphous silicon carbide system electrophotographic image-forming members.
