Abstract
A process for manufacturing a photoreceptor for electrophotography excellent in electrophotographic characteristics such as charging properties and sensitivity, which process comprises the steps of forming on a substrate, which comprises an electroconductive support or a support having an electroconductive film thereon, a thin film composed of a material selected from the group consisting of silicon dioxide and silicon oxides, containing predominantly SiO.sub.2, by deposition from the vapor phase to produce an under coat layer, and forming on said under coat layer a carrier generation layer and a carrier transport layer in this order.
Claims5
A photoreceptor for electrophotography comprising, in order:
- a substrate which comprises an electroconductive support or a support having an electroconductive film formed thereon;
- an under coat layer including a material selected from a group consisting of silicon dioxide and other silicon oxides formed on said substrate;
- a carrier generation layer formed on said under coat layer;
- and
- a carrier transport layer formed on said carrier generation layer.
