摘要：
An electrophotographic photosensitive member is disclosed having a cylindrical support and an organic photosensitive layer provided on the cylindrical support. The peripheral surface of the electrophotographic photosensitive member is composed of grooves formed substantially in its peripheral direction and flat portions, and in the grooves, the number of grooves each having a width in the range of from 0.5 μm to 40 μm is from 20 to 1,000 lines per 1,000 μm in width in the generatrix direction of the peripheral surface of the electrophotographic photosensitive member.
