Patent ID: 7449271

Claim:
A photoconductor for electrophotography having resistance to solvent cracking upon exposure to at least one of liquid developers and cleaning solvents, the photoconductor comprising: a conductive substrate; and a photosensitive layer comprising a charge generation material, a charge transport material, and a resin binder comprised of polyarylate resin having structural units represented by formula (I): wherein each of R 1 and R 2 , being identical or different from each other, is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a cycloalkyl group, a substituted cycloalkyl group having at least one substituent, an aryl group and an aryl group having at least one substituent; wherein R 1 , R 2 , and a carbon atom that bonds to both R 1 and R 2 , form a cyclic structure that is bonded to no more than two arylene groups; wherein each of R 3 through R 10 , being identical or different from each other, is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a fluorine atom, a chlorine atom and a bromine atom; and wherein m and n satisfy the equation 0.55≦m/(m+n)≦0.65.
