A layered photosensitive imaging member is modified by forming a low-reflection layer on the ground plane. The low-reflection layer serves to reduce an interference fringe contrast and according to a second aspect of the invention, layer adhesion is greatly improved when selecting TiO.sub.2 as the low-reflection material. In a preferred embodiment, low-reflection materials having index of refraction greater than 2.05 were found to be most effective in suppressing the interference fringe contrast.

Photosensitive imaging member

A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane surface with a rough surface morphology by various selective deposition methods. In one method the metal forming the ground plane is deposited through a fine mesh screen which is either held stationary during a single pass or alternatively vibrated at a specific frequency during a single pass of deposition. Light reflected from the ground plane formed with the rough surface morphology is diffused through the bulk of the photosensitive layer breaking up the interference fringe patterns which are later manifested as a plywood pattern on output prints made from the exposed sensitive medium.

Plywood effect suppression in photosensitive imaging members

A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane of a low-reflecting material such as tin oxide or indium tin oxide. An additional feature is to add absorbing materials to the dielectric material upon which the ground plane is formed to absorb secondary reflections from the anti-curl back coating layer air interface.
