Abstract
In an electrophotographic photosensitive member having a photoconductive layer and, provided on the photoconductive layer, a surface layer constituted of a hydrogenated amorphous silicon carbide, the ratio of the number of atoms of carbon atoms (C) to the sum of the number of atoms of silicon atoms (Si) and number of atoms 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 6.60×1022atom/cm3 or more.
