Abstract
An electrophotographic photoreceptor including 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. The hole transport protective layer includes a three-dimensionally crosslinked material obtained by irradiating a composition including at least a radically polymerizable hole transport compound with ultraviolet rays or electron beams so that the radically polymerizable hole transport compound causes chain polymerization. In addition, the protective layer includes a specific cyano-containing styryl aromatic compound or a specific cyano-containing distyryl aromatic compound.
