Abstract
An organic photosensitive member for electrophotography is provided which comprises a photosensitive layer 3 formed on an electroconductive substrate 1 via an undercoating layer 2, the photosensitive layer 3 comprising a charge generating layer 4 and a charge transporting layer 5, wherein the undercoating layer 2 consists essentially of 12/6/66 copolymeric polyamide expressed by the general formula (I) ##STR1## and a styrene/maleic acid half ester copolymer. By providing such an undercoating layer, it becomes possible to obtain a photosensitive member having excellent electrophotographic characteristics, involving minimal changes in these characteristics during repeated use, and giving a high quality image stably.
