ABSTRACT:
A piezo-active charge retentive member, such as a photoreceptor, has a grounded electrode layer separating a photoreceptive layer and a piezo-active layer. External vibration sources become unnecessary since supplying an A.C. voltage across the piezo-active layer to the grounded electrode layer causes the piezo-active layer, and thus the entire photoreceptor, to vibrate. Vibration of the photoreceptor enhances the transfer of development powder from the photoreceptor to the transfer material, such as a sheet of paper. Vibration of the photoreceptor also improves the development of images and assists the cleaning of residual development powder from the photoreceptor surface.
