摘要：
A surface layer of the electrophotographic photosensitive member has a change region in which a ratio of the number of carbon atoms with respect to the sum of the number of silicon atoms and the number of carbon atoms gradually increases toward a surface side of the electrophotographic photosensitive member from a photoconductive layer side, wherein the change region has an upper charge injection prohibiting portion containing a Group 13 atom, and a surface-side portion which is positioned closer to the surface side of the electrophotographic photosensitive member than the upper charge injection prohibiting portion and does not contain the Group 13 atom, and the distribution of the Group 13 atom in a boundary portion between the surface-side portion and the upper charge injection prohibiting portion is precipitous.
