Abstract

An apparatus in which a donor roll advances toner to an electrostatic latent image recorded on a photoconductive member. A plurality of electrode wires are positioned in the space between the donor roll and the photoconductive member. The electrode wires are electrically biased to detach the toner from the donor roll so as to form a toner cloud in the space between the electrode wires and photoconductive member. Detached toner from the toner cloud develops the latent image. A damping material is coated on a portion of the electrode wires. The damping material damps vibration of the electrode wires.
