Abstract
A separate-function laminate-type photoconductor for electrophotography includes a photosensitive substrate having a subbing layer and a photosensitive layer laminated on the substrate in this order, in which the subbing layer is composed of a resin containing phosphorus in an amount within the range of 30 to 500 ppm by weight based on the resin. The resin for the subbing layer is preferably an epoxy resin. The photoconductor has a high sensitivity, a good ability to electrified and a low residual potential, and gives less variation in its characteristics due to environmental factors to give an image of a good quality constantly.
