Patent ID: 8173343

Claim:
An electrophotographic photoconductor comprising: a support; at least a photosensitive layer; and a surface protective layer, the photosensitive layer and the surface protective layer being laid over the support, wherein the surface protective layer comprises a filler, a charge transporting material, and a compound represented by any one of General Formulas (1) and (2), and wherein the photosensitive layer comprises at least a charge transporting material having an oxidation potential lower than the oxidation potential of the charge transporting material contained in the surface protective layer and is a compound represented by General Formula (3), wherein: R 1 and R 2 may be identical to or different from each other, each represent any one of an alkyl group that may have a substituent and an aryl group that may have a substituent; at least one of R 1 and R 2 is an aryl group that may have a substituent; R 1 and R 2 may be bonded to each other to form a heterocyclic ring containing a nitrogen atom, and the heterocyclic ring may be further substituted with a substituent; and Ar represents an allylene group that may have a substituent, wherein: R 1 and R 2 may be identical to or different from each other, each represent any one of an alkyl group that may have a substituent and an aryl group that may have a substituent; R 1 and R 2 may be bonded to each other to form a heterocyclic ring containing a nitrogen atom, and the heterocyclic ring may be further substituted with a substituent; Ar 1 and Ar 2 each represent an allylene group that may have a substituent; l and m each represent an integer of 0 to 3, both of which are not zero at the same time; and n is an integer of 1 or 2, wherein: R 3 to R 6 each represent any one of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, and a phenyl group that may have a substituent; and A represents any one of an allylene group that may have a substituent and a substituent represented by Structural Formula (3-1), wherein: R 7 , R 8 and R 9 each represent any one of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, and a phenyl group, the phenyl group may be further substituted with a substituent; and B represents any one of an aryl group that may have a substituent, and a substituent represented by Structural Formula (3-2), wherein: Ar 3 represents an allylene group that may have a substituent; and Ar 4 and Ar 5 each represent an aryl group that may have a substituent.
