Abstract:
An organic photoconductor comprising a cylindrical electrically conductive support and, formed thereon in this order, a charge-generating layer and a charge-transporting layer, the external surface of said cylindrical electrically conductive support having an index of surface area as defined by the following equation (I) of from 0.01 to 0.10, and said charge-generating layer having a multilayer structure comprising a charge-generating layer having n-type semiconductor characteristics and a charge-generating layer having p-type semiconductor characteristics:(Sa/Sm)âˆ’1â€ƒâ€ƒ(I) wherein Sa is the actual surface area of the external surface of said cylindrical electrically conductive support and Sm is the theoretical surface area thereof calculated on the assumption that said support is an ideal cylinder.
