Abstract
An electrophotographic device for reproducing an image on an imaging member includes: processing elements for forming a toner-developed latent image on a charge retentive surface of the imaging member; a transfer station for transferring toner from the imaging surface to a second surface of a receiving member; an arrangement for enhancing toner release from the imaging surface, including a resonator in contact with and applying vibratory energy to the imaging member at a location at which toner release is desired having a resonator resonant frequency f.sub.r ; a coupler for coupling the imaging member to the resonator; a driving signal source electrically coupled to the resonator, and producing a driving signal selected to drive the resonator at frequency f.sub.r ; the imaging member, coupler and receiving member together defining a system having a first and second belt resonant frequency (f.sub.b1 and f.sub.b2, respectively) when excited by the toner release enhancer; and the belt resonant frequencies and the resonator resonant frequency selected so that
