ABSTRACT:
An electrophotographic device includes a flexible belt-type charge retentive member, bearing a developed latent image and brings a sheet of paper or other transfer member into intimate contact with the charge retentive surface at a transfer station for electrostatic transfer of toner from the charge retentive surface to the sheet. At the transfer station, a resonator suitable for generating vibratory energy is arranged in line contact with the back side of the charge retentive, to uniformly apply vibratory energy to the charge retentive member surface at a position opposite the transfer coronode or peak transfer field, or slightly upstream therefrom. Toner is released from the electrostatic and mechanical forces adjering it to the charge retentive surface at the line contact position.
