Patent ID: 7090952

Claim:
An electrophotosensitive material comprising a conductive substrate and a photosensitive layer provided on the conductive substrate, wherein the photosensitive layer contains a polyarylate having a repeating unit represented by the general formula (1): in the formula (1), X represents any of divalent groups represented by the formulas (b) or (c): and R 1 and R 2 are the same or different and represent an alkyl group having 1 to 3 carbon atoms, and a hole transferring material having a triphenylaminostyryl group represented by the general formula (h1): in the formula (h1), R ha and R hc are the same or different and represent an alkyl group having 1 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, or an aryl group having 12 or less carbon atoms and, in case two or more of the substituents R ha and R hc are substituted on the same benzene ring, the substituents R ha and R hc substituted on adjacent carbon atoms may be combined with each other to form a saturated or unsaturated hydrocarbon ring, and a represents an integer of 0 to 3, in the molecule.
