摘要： PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor, a process cartridge and an electrophotographic device made excellent in wear and abrasion resistance, flaw resistance and deposition resistance, hardly causing trouble on an image in the case of repetitive use and made good in the gradation of developed image density.
SOLUTION: In the electrophotographic photoreceptor having a photoreceptive layer on a conductive supporting body, the photoreceptive layer is a functional separation type one obtained by laminating a charge generating layer and a charge transporting layer in this order, and the charge transporting layer has constitution where two or more layers are laminated, and an outermost layer incorporates a charge transporting compound and a compound including an acryloyl oxy-radical (CH
2 =CHCOO-) or a methacryloyl oxy-radical (CH
2 =C(CH
3 )COO-), and is hardened by electron beam irradiation. The process cartridge and the electrophotographic device having the electrophotographic photoreceptor are obtained.
