PROBLEM TO BE SOLVED: To provide an excellent electrophotographic photoreceptor which has high durability and high service life and does not cause problems such as an image flow under high humidity and a black band under an electrostatic charger. SOLUTION: The electrophotographic photoreceptor has a support and a photosensitive layer provided on the support, in which the uppermost surface layer of the electrophotographic photoreceptor has a polymer prepared by polymerizing a compound (A): a hole transport compound having two or more chain polymerizable functional groups within the same molecule and a compound (B): a compound having the chain polymerizable functional group and an arylene ether group, not having a hydroxyl group, having a functional group of constitutional formula (1) between the chain polymerizable functional group and the arylene group and not having the hole transport function. In the formula (1), v and w show an integer from 0 to 5, in which the sum of v and w is an integer of 2 to 5. COPYRIGHT: (C)2007,JPO&INPIT
