Electrophotographic photosensitive member, process cartridge and electrophotographic image forming apparatus

A process cartridge comprising:

• an electrophotographic photosensitive member comprising a support and a surface layer, wherein the surface layer comprises a compound represented by following formula (1);
• and
• at least one unit selected from the group consisting of a charging unit, a developing unit, a transfer unit, and a cleaning unit,
• the process cartridge integrally supporting the electrophotographic photosensitive member and the at least one unit, and being detachably attachable to a main body of an electrophotographic apparatus:
• where, in the formula (1),
• R11 to R13 each independently represent an alkylene group having 1 to 6 carbon atoms, and
• Q11 to Q13 each independently represent a hydroxy group or a carboxy group.
