Abstract

An electrophotographic photoreceptor of high durability capable of providing stable excellent electrical characteristics over a prolonged period of time, which electrophotographic photoreceptor excels in mechanical strength. A photosensitive layer (14) of an electrophotographic photoreceptor (1) includes a polyarylate resin having structural units, for example, those of formula (1)and an enamine compound represented by, for example, formula (2)The variables R1, R2, R3, R4, R7˜R10, X1, Ar1, Ar2, Ar3, Ar4, Ar5, R11, R12, R13, R14, a, m, and n are as defined in the specification. By virtue of these, the electrophotographic photoreceptor (1) of excellent mechanical strength and favorable electrical characteristics can be realized.
