Patent ID: 7629095

Claim:
An electrophotographic imaging member comprising, in order: a substrate, a conductive layer, a charge generating layer, and a charge transport layer, wherein the charge generating layer comprises: a photogenerating material and a hydroxyl group-containing polycarbonate resin comprising free hydroxyl groups in an amount of from about 10 to about 75 mol %; a film-forming polymeric binder that is different from the hydroxyl group-containing polycarbonate resin; and the hydroxyl group-containing polycarbonate resin comprises at least one repeating segment represented by the formula (I): wherein R 1 is selected from the group consisting of hydrogen, alkyl, and aryl; R 2 represents a divalent linkage selected from the group consisting of alkylene optionally containing one or more heteroatoms of halogen, nitrogen, sulfur, silicon, or phosphorus, arylalkylene, and arylene; Ar 1 and Ar 2 each independently represent aromatic groups; and P represents a hydrogen atom, or a hydroxyl protective group.
