Electrophotographic photosensitive member, production method of electrophotographic photosensitive member, process cartridge and electrophotographic apparatus

A production method of an electrophotographic photosensitive member having a support, a charge generation layer, a charge transport layer and a surface layer in the listed order,

• the production method comprising:
• preparing a coating liquid for a surface layer, which contains a hole transporting compound having an acryloyloxy group or a methacryloyloxy group, and a compound represented by formula (1) or (2) in an amount of 50 to 4000 ppm based on a total solid content in the coating liquid:
• H3C—(CH2)a—COOH (1)
• H3C—(CH2)b—OH (2)
• wherein in the formula (1), a is an integer of 6 or more;
• and in the formula (2), b is an integer of 6 or more;
• forming a coating film of the coating liquid for the surface layer;
• and
• curing the coating film to thereby form the surface layer of the electrophotographic photosensitive member.
