Abstract:
1. An electrophotographic photoreceptor comprising: an electroconductive substrate; a charge generation layer located overlying the electroconductive substrate; a hole transport layer located on the charge generation layer; and a hole transport protective layer located on the hole transport layer, and including an UV or EB crosslinked material including a unit obtained from a radically polymerizable hole transport compound, and a cyano compound (C) having the following formula (1) or (2): wherein Ar wherein Ar wherein the UV or EB crosslinked material is obtained by irradiating a composition including at least the radically polymerizable hole transport compound with ultraviolet rays or electron beams so that the radically polymerizable hole transport compound causes chain polymerization, wherein a weight ratio (C/RHTM) of the cyano compound (C) to the radically polymerizable hole transport compound (RHTM) is from 0.005/1 to 0.1/1.
