  • Method and apparatus for xerographic reproduction
    Patent number: 3970381
    Abstract: Improved stripping of a transfer member (having a developed image thereon) from a photoconductive surface of an electrostatic reproduction machine is effected by charging the lead edge of the member with a first charge, and then charging the body of the member having the developed image thereon with a second charge which is different than the first charge. The second charge has a magnitude and polarity which prevents retransfer of the developed image to the photoconductive surface.
