Abstract
An electrophotographic photosensitive member includes a photoconductive layer, an intermediate layer, and a surface layer. When Si+C atom density in the surface layer is represented by DS×1022 atoms/cm3, the DS is 6.60 or more, and when the maximal value of H/(Si+H) in a distribution of hydrogen quantity in the photoconductive layer in a layer thickness direction is represented by HPmax, the average value of the H/(Si+H) in the second photoconductive region is represented by HP2, the DS and the HP2 satisfy the following expression (1) and the DS and the HPmax satisfy the following expression (2).HP2≧0.07×DS−0.38 Expression (1)HPmax≦0.04×DS+0.60 Expression (2)
