Abstract
An apparatus in which an electrostatic latent image recorded on a photoconductive belt is developed with toner. A donor belt is wrapped about a portion of a magnetic roll to define an extended loading zone. The magnetic roll advances a developer material comprising carrier and toner to the loading zone. At the loading zone, toner is deposited on the donor belt. A plurality of electrode wires are positioned in the space between the donor belt and the photoconductive belt. The electrodes are electrically biased to detach the toner from the donor belt so as to form a toner cloud in the space between the electrodes and photoconductive belt. Detached toner from the toner cloud develops the latent image.
