ABSTRACT:
In a scavengeless development apparatus, an electrode wire is disposed between a donor roll and a latent image to form a powder cloud of toner to develop the latent image. The donor roll includes a section of increased diameter spaced away from the latent image, and the electrode wire is disposed in sliding contact with the section of increased diameter to obtain a consistent spacing from the main length of the donor roll.
