Abstract
An improved electrophotographic process, where the image to be reproduced is transferred onto a photoconductive support as an image of electric charges, in which image of charges is transferred from a photoconductive support in virtual contact with a dielectric support to the dielectric support, the improvement comprising completely discharging the photoconductive support before or at the instant of separation of the dielectric support and photoconductive support. The electrophotographic reproduction apparatus of the present application comprises means for producing an electrostatic image on a dielectric support means to bring said dielectric support into virtual face-to-face contact with a photoconductive support, means to transfer the electrostatic image to the dielectric support from the photoconductive support, and means to completely discharge the photoconductive support subsequent to the transfer of charges but before the separation of the dielectric support and photoconductive support.
