<P>PROBLEM TO BE SOLVED: To provide a photoreceptor with which deviation of image density in a surface is reduced, and which enables image output of high definition, and further a process cartridge which copes with a high definition, a high speed, and stability upon mass printing required in the commercial printing field. <P>SOLUTION: In the electrophotographic photoreceptor, at least a charge generation layer, a first charge transport layer, and a second charge transport layer are sequentially laminated on an electroconductive substrate. The first charge transport layer is mainly formed from a molecular dispersion film in which a low molecular charge transport material is contained in a binder resin. The second charge transport layer is formed from a crosslinked film obtained by irradiating ultraviolet radiation to a composition, which is obtained by mixing at least a radically polymerizable charge transport compound, a tri- or more functional radically polymerizable monomer, and a photopolymerization initiator together, to cause a radical curing reaction. The crosslinked film contains a 2,5-diaryl-1,3,4-oxadiazole derivative. <P>COPYRIGHT: (C)2011,JPO&INPIT |
