ABSTRACT:
A vapor-deposited film of selenium or selenium alloy as a photoreceptor for electrophotography comprises selenium or a selenium alloy and phosphorus contained therein in an amount of not less the 0.5 ppm and adjusted to attain a desired contrast potential. The selenium alloy is selected from Se-Te, Se-As, Se-Bi, and Se-Sb alloys. The film is produced either by adding phosphorus to stock selenium or selenium alloy and then vacuum-depositing the phosphorus-containing selenium or selenium alloy or by simultaneously vapor-depositing selenium or selenium alloy and elemental phosphorus or a phosphorus compound.
