    摘要: Provided is an electrophotographic photosensitive member having excellent cleaning performance, and a process cartridge and an electrophotographic apparatus, each including the electrophotographic photosensitive member.The peripheral surface of the electrophotographic photosensitive member has a plurality of flat portions having a width e (μm) that satisfies the relationship 0.1≦e≦25 and a plurality of groove portions having a width w (μm) that satisfies the relationship 0.1≦w≦25 and a depth d (μm) that satisfies the relationship 0.1≦d≦3.0, the flat portions and the groove portions being alternately formed at an angle θ (°) that satisfies the relationship 80≦θ≦100 with respect to the axial direction of the electrophotographic photosensitive member. The sum esum (μm) of the widths e of the flat portions per each width of 100 μm in the axial direction of the peripheral surface satisfies the relationship 5≦esum≦75, and eσ/eAv satisfies the relationship eσ/eAv≦0.46, where eAv (μm) is the average value of the widths e of the flat portions, and eσ is the standard deviation thereof.
