Abstract
An electrophotographic photosensitive member is configured such that the average value Hx_ave of the content of hydrogen atoms in a central portion area of a photoconductive layer in a cylindrically axial direction thereof, the content Hx of the hydrogen atoms at an arbitrary point in the central portion area, the average value Hy_ave of the content of the hydrogen atoms in an end area of the photoconductive layer in the cylindrically axial direction thereof, and the content Hy of the hydrogen atoms at an arbitrary point in the end area satisfy 10≦Hx_ave≦30, Hx<Hy, |Hx_ave−Hx|≦5, and 2≦Hy_ave−Hx_ave≦12.
