Abstract
Provided is an electrophotographic photosensitive member that can suppress the generation of both an interference fringe and a streaky uneven part in a circumferential direction on an image. The generation of the interference fringe and the generation of the streaky uneven part in the circumferential direction on the image are suppressed by defining a length of a line-shaped groove of a support in a circumferential direction, and defining roughness parameters of a support in an axial direction.
