Patent ID: 7160658

Claim:
An electrophotographic photoreceptor comprising: an electroconductive substrate; and a photosensitive layer disposed above the electroconductive substrate; wherein an outermost surface layer of the electrophotographic photoreceptor contains an inorganic filler and a copolymer polyarylate resin having an alkylene-aryldicarboxylate structural unit as a binder resin, wherein the copolymer polyarylate resin having the alkylene-aryldicarboxylate structural unit is represented by the following general formula I: where Ar 1 , Ar 2 and Ar 3 represent aryl groups which may have a substituent, the substituent group representing one of halogen atom and alkyl group, and X represents a bivalent alkyl group; l and m are mol ratios fulfilling 0.05≦1<0.6, 0.4≦m<0.95, and l+m=1.
