Electrophotographic photosensitive member and electrophotographic apparatus

Abstract

Provided is an electrophotographic photosensitive member that improves the sensitivity characteristic and high-humidity deletion resistance, and achieves compatibility between a high image-resolving power and the suppression of an image memory. The electrophotographic photosensitive member comprises an electrophotographic photosensitive member, including: a photoconductive layer; and a surface layer comprising hydrogenated amorphous silicon carbide on the photoconductive layer, in which: a ratio (C/(Si+C)) of a number of carbon atoms (C) to a sum of a number of silicon atoms (Si) and the number of the carbon atoms (C) in the surface layer is 0.50 or more and 0.65 or less; a sum of an atom density of the silicon atoms and an atom density of the carbon atoms in the surface layer is 6.60×1022 atoms/cm3 or more; and a defect density of the surface layer determined by electron spin resonance measurement is 9.0×1018 spins/cm3 or more and 2.2×1019 spins/cm3 or less.
