Abstract

An electrophotographic photosensitive member includes a photoconductive layer and, provided on the photoconductive layer, a surface layer containing a hydrogenated amorphous silicon carbide. A ratio of the number of carbon atoms (C) to the sum of the number of silicon atoms (Si) and number of carbon atoms (C), C/(Si+C), in the surface layer is from 0.61 or more to 0.75 or less, and the sum of atom density of the silicon atoms and atom density of the carbon atoms in the surface layer is 6.60×1022 atom/cm3 or more.
