ABSTRACT:
There is described an electrophotographic photoreceptor comprising a conductive metallic substrate, a composite interfacial structure made up of a layer comprising organic thermoplastic polymeric adhesive material and a thin layer of arsenic triselenide, and a photoconductive insulating layer comprising selenium or its alloys. The photoreceptor is formed by a method which includes depositing the arsenic triselenide layer while the substrate temperature is held at or above the softening point of the thermoplastic polymeric adhesive material but below the crystallization temperature of the arsenic triselenide and then depositing a layer of selenium or selenium alloy while the substrate temperature is held below the softening point of adhesive material and below the crystallization temperature of the selenium or selenium alloy. The photoreceptor exhibits a strong mechanical bond between the adhesive material and the arsenic triselenide layer and a strong bond between the arsenic triselenide and the photoconductive layer.
