Abstract

Disclosed is a method of treating an electrostatographic photoreceptor comprised of. a conductive substrate having a layer of an amorphous selenium/arsenic alloy on and in opera-tive contact with its surface which method comprises heating the photoreceptor to a temperature of from 60°Cto 150°Cfor a period of time greater than 2 hours in an oxygen containing atmosphere to thereby reduce the arsenic concentration in the selenium/arsenic at the near surface of the selenium/arsenic layer.
