Abstract
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.
