Electrophotographic photoreceptor, process cartridge, and electrophotographic apparatus

電子写真感光体、プロセスカートリッジ及び電子写真装置

Abstract

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor in which mechanical strength and electrophotographic properties of a curable film having charge transport property are further exhibited and on which image defects including image deletion do not occur even with repetitive use in a high temperature and high humidity environment, and to provide a process cartridge equipped with the same and an electrophotographic apparatus. SOLUTION: The electrophotographic photoreceptor comprises a conductive support body and a photosensitive layer formed on the conductive substrate, a top surface layer of the electrophotographic photoreceptor contains a compound obtained by polymerizing and crosslinking a charge transport compound having at least an acryloyloxy group or a methacryloyloxy group and a compound having one or more hydroxyl groups in the same molecule, and a content of the compound having one or more hydroxyl groups in the same molecule is 5-45% on the basis of the total mass of the top surface layer.
