An imaging device having a non-rigid member with a charge retentive surface moving along an endless path, an imaging system for creating a latent image on the charge retentive surface, a developer for imagewise developing the latent image with toner, a transfer system for electrostatically transferring the developed toner image to a copy sheet, and a resonator for enhancing toner release from the charge retentive surface, producing relatively high frequency vibratory energy and having a portion thereof adapted for contact across the flexible belt member, generally transverse to the direction of movement thereof, the resonator includes a horn member for applying the high frequency vibratory energy to the non-rigid member, having a platform portion, a horn portion, and a contacting portion and extending across the non-rigid member. Vibratory energy producing device is coupled to said horn platform for generating the high frequency vibratory energy required to drive said horn member, the vibratory energy producing device includes a piezoelectric polymer film material. And, a voltage source is provided for driving the vibratory energy producing device.
