摘要： An apparatus which transfers successive different color toner images from a photoconductive belt (20) to a sheet. The toner images are in superimposed registration with one another by means of a sheet transport apparatus (48) which moves the sheet in a recirculating path. Transfer efficiency of successive toner images is improved by neutralizing the charge on the toner image prior to the transfer of the next successive toner image to the sheet. This is accomplished by passing the sheet with the toner image transferred thereto between upper and lower neutralization corona generators (64, 65). The upper neutralization corona generator (64) applies a charge on the toner image having an opposite polarity to the normal polarity of the toner image. The lower neutralization corona generator (65) applies a charge on the backside of the sheet having the same polarity as the normal polarity of the toner image.

摘要： A novel wire module support structure for controlling the spacing and edge wire angle of an electrode wire (42) relative to a donor roll (40) in a scavengeless development process is disclosed. A stationary wire support (100) is arc shaped with a rounded edge and is located in close proximity to the donor roll end. This spatial relationship between the donor roll end and the wire support surface (102) optimizes the donor roll surface to wire relationship. The wire support surface (102) may be at a greater or lesser radius than the the donor roll surface. When the wire support surface is located at a larger radius than the donor roll surface, a clamp assembly (200) is used to control the height of the wires with respect to the donor roll surface.
