Abstract

The use of constant pressure in photoreceptor fabrication processing during alloy coating evaporation and deposition steps produces greater uniformity in coating thickness and produces enhanced photosensitivity in the xerographic properties.

The use of constant pressure in photoreceptor fabrication processing during alloy coating evaporation and deposition steps produces greater uniformity in coating thickness and produces enhanced photosensitivity in the xerographic properties.

An automatic pressure controller is used to maintain a constant partial vacuum within a vacuum alloy coating apparatus. When the pressure of the coating process is not kept constant variability in: film coating thickness; surface roughness; and xerographic electrical properties, for example, dark decay potentials, are observed.
