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.

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.

Treatment of the photoreceptor as above described signif-
icantly reduces or eliminates print deletion problems some-
times associated with the use of selenium/arsenic photoconduc-
tors.
