ABSTRACT:
In an electrophotographic photosensitive device including a conductive layer, a selenium based photoconductive layer and a transparent insulating layer which are sequentially laminated, the conductive layer is formed of an aluminum substrate conductive layer, a zinc conductive layer a copper conductive layer, and silver conductive layer which are sequentially laminated to each other. As a result of this structure, the charge injection characteristic of the photosensitive device during primary charging is improved, and the charge injection preventing characteristic during the simultaneous secondary charging and image exposure steps is sufficiently maintained. The conductive layers contact each other intimately. The electrophotographic photosensitive device is highly humidity durable and exhibits a long life and can obtain high electrostatic contrast.
