Electrophotographic photosensitive member, process cartridge, and electrophotographic apparatus

A process cartridge, integrally supporting an electrophotographic photosensitive member and at least one unit selected from the group consisting of a charging unit, a developing unit, and a cleaning unit, and being detachably attachable to a main body of an electrophotographic apparatus

• the electrophotographic photosensitive member comprising:
• a support with a cylindrical shape;
• and a photosensitive layer, wherein
• the support has a surface formed of Al and/or an Al alloy, and
• the surface of the support includes an Al crystal grain having
• (α) plane having {001} orientation of −15° or more and less than +15°,
• (β) plane having {101} orientation of −15° or more and less than +15°, and
• (γ) plane having {111} orientation of −15° or more and less than +15°,
• a ratio of an area occupied by an Al crystal grain having (γ) to the total area of the surface of the support is 10% or less, and a ratio of an area occupied by any one of an Al crystal grain having (α) and an Al crystal grain having (β) is 60% or more.
