An electrophotographic photoreceptor comprising a conductive layer and a photosensitive layer of vapor-deposited selenium-antimony alloy film formed thereon is disclosed. The photosensitive layer has an average antimony concentration of 5 to 21 wt % and the center layer thereof except for the skin layer on either side has a change in antimony concentration within 2 wt % in any region that is 1000 deep .ANG. from the surface of the skin layer.

Selenium-antimony alloy electrophotographic photoreceptors

An electrophotographic element having a conductive support upon which a coating of oleophilic resin-encapsulated zinc oxide particles, and a sensitizer dispersed in a binder containing vinyl chloride and vinyl acetate polymers is disclosed. Capsule wall can be 5A to 1.mu. thick. The oleophilic resin can be silicone, urethane, epoxy.
