Electrophotographic photoconductor
摘要:
An electrophotographic photoconductor containing 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 contains a charge transporting material (M) and a binder resin (B) and further has a layered structure composed of a plurality of the charge transporting layers wherein the outermost layer of the charge transporting layers show 50% or higher elastic power (ηHu) and hardness (Hplast) of plastic deformation in a range from 220 N/mm2 or higher to 275 N/mm2 or lower.
