ABSTRACT:
A process for fabricating an electrophotographic imaging member is disclosed comprising providing in a vacuum chamber at least one crucible containing particles of an alloy comprising selenium and an alloying component selected from the group consisting of tellurium, arsenic, and mixtures thereof, providing a substrate in the vacuum chamber, applying a partial vacuum to the vacuum chamber, and rapidly heating the crucible to a temperature between about 250.degree. C. and 450.degree. C. to deposit a thin continuous selenium alloy layer on the substrate. A plurality of selenium containing layers may be formed by providing in a vacuum chamber at least one first layer crucible containing particles of selenium or a sellenium alloy, at least one second layer crucible containing particles of an alloy comprising selenium, and a substrate, applying a partial vacuum to the vacuum chamber, heating the particles in the first layer crucible to deposit a thin continuous selenium or a selenium alloy first layer on the substrate, maintaining the particles in the second layer crucible at a first temperature below about 130.degree. C. while the thin continuous selenium or a selenium alloy first layer is being deposited on the substrate, and rapidly heating the particles in the second layer crucible to a second temperature between about 250.degree. C. and about 450.degree. C. to deposit a thin continuous selenium alloy second layer on the substrate.
