Abstract
A laminated-type photosensitive member having an aluminum substrate, and a charge generating layer comprised of an organic pigment dispersed in resin, and a charge transporting layer, the aluminum substrate is anodized to form a alumite layer which has a certain thickness, a certain crystalline/amorphous aluminum oxide molar ratio, and a certain impedance; the anodized aluminum layer is sealed; and/or an undercoat layer is formed on the anodized layer. By such arrangement it is possible to obtain a laminated-type photosensitive member excellent in properties of photosensitive members, in particular, good anti-charge injection and retification characteristics.
