Patent ID: 7638248

Claim:
An electrophotographic photoconductor comprising a conductive substrate and at least a charge generating layer and a charge transporting layer successively layered on the substrate, wherein the charge transporting layer comprises a charge transporting material (M) and a binder resin (B) which contains, as a main component, a compound represented by the general formula (1): in which R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 , may be the same or different each other and each independently denote a hydrogen atom, a halogen atom, or a substituted or unsubstituted C 1 to C 6 alkyl group; and R 9 and R 10 may be the same or different each other and each independently denote a hydrogen atom, a halogen atom, a substituted or unsubstituted C 1 to C 6 alkyl group, a saturated cyclic C 4 to C 10 hydrocarbyl group, or a substituted or unsubstituted aryl group; and n denotes an integer: and further has a layered structure composed of a plurality of said charge transporting layers wherein the outermost layer of the said charge transporting layers shows 50% or higher elastic power (η HU ) measured in the surface coating hardness test by applying a highest pushing load of 5 mN to the surface layer at ambient temperature of 25° C. and at 50% relative humidity and hardness (Hplast) of plastic deformation in a range from 220 N/mm 2 or higher to 275 N/mm 2 or lower; wherein the charge transporting material has an enamine structure represented by the following formula (2):
