Abstract
An electrophotographic photoreceptor includes a conductive substrate, a charge-generating layer disposed on the conductive substrate, and a charge-transporting layer as an outermost layer disposed on the charge-generating layer and containing a binder resin and a charge-transporting material, wherein the average particle size of the crystal of the charge-transporting material is approximately from 0.1 μm to 5.0 μm.
