摘要： An electrophotographic photosensitive member includes a substrate, a photoconductive layer, an intermediate layer, and a surface layer sequentially formed. The intermediate layer contains silicon, carbon and hydrogen, and a distribution of a hydrogen ratio, which is a ratio of the number of hydrogen atoms to the number of silicon, carbon and hydrogen atoms, in the intermediate layer has a maximum region. A largest hydrogen atomic ratio in the intermediate layer is larger than a hydrogen atomic ratio in the surface layer, and the hydrogen atomic ratio in the surface layer is 0.30 to 0.45. A distribution of a carbon atomic ratio, which is a ratio of the number of carbon atoms to the number of silicon and carbon atoms, in the intermediate layer has a maximum and a minimum region. A carbon atomic ratio in the maximum region is 0.53 to 0.63, a carbon atomic ratio in the minimum region is 0.47 or more, and the maximum hydrogen region in the intermediate layer is partially superimposed on the minimum carbon region.

摘要： An electrophotographic light-receiving member has a conductive support and a photoconductive layer composed of a non-monocrystalline material comprising silicon atoms as a matrix, hydrogen and/or halogen atoms, and an element belonging to Group IIIb of the periodic table. The photoconductive layer has from the surface side toward the conductive support side, a third layer region that absorbs 50-90% of incident image exposure light and a second layer region that absorbs 60-90% of pre-exposure light incident on the photoconductive layer. The Group IIIb element is present such that its content decreases from the conductive support side to the surface side. In three embodiments the photoconductive layer has, respectively: 10-30 at. % H; 10-20 at. % H and 25-40 at % H; an optical band gap of 1.75-1.85 eV, 1.65-1.75 eV and 1.80-1.90 eV and a characteristic energy of each of 50-55 meV.
