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 tensioned. An electrical bias is applied to the electrode wires to detach the toner from the donor rolls so as to form a toner cloud in the space between the electrode wires and the photoconductive member. Detached toner from the toner cloud develops the latent image. Vibration of the electrode wires is detected in order to enable the vibration of the electrode wires to be substantially cancelled.
