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 causes a carrier bead bouncing effect where carrier beads from the developer collide with the photoreceptor in the development area. The carrier bear bouncing effect increases the number of carrier bead-toner-photoreceptor contact events during development of the photoreceptor's latent image.
