(57) [Summary] [PROBLEMS] To suppress a reduction in life due to filming on the outermost surface layer of a photoreceptor and improve filming resistance while maintaining mechanical durability and wear resistance. SOLUTION: In an electrophotographic photosensitive member having a photosensitive layer on a conductive substrate, the photosensitive layer has the following formula (I-1): (Wherein, R is an alkyl group, etc., B is (CH 2 ) x , x is 2 to 6, n is 0 to 200, and m is 1 to 50). contains. |
