ABSTRACT:
An apparatus which transfers successive different color toner images from a photoconductive belt to a sheet. The toner images are in superimposed registration with one another. 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. The upper neutralization corona generator applies a charge on the toner image having an opposite polarity to the normal polarity of the toner image. The lower neutralization corona generator applies a charge on the backside of the sheet having the same polarity as the normal polarity of the toner image.
