ABSTRACT:
A method for enhancing the contrast of a latent electrostatic image on a dielectric surface is disclosed which includes positioning a photoconductive electrode adjacent the dielectric surface; and applying an electrical potential between the photoconductive member and the dielectric surface, while irradiating selected portions of the photoconductive electrode, to cause electrical charge formation on selected portions of the dielectric surface corresponding to the selected photoconductive electrode portions. Thereafter, the applied electrical potential is reduced to essentially zero. In accordance with this invention, during such reduction to essentially zero potential, the entire surface of the photoconductive member is briefly flooded with light to obtain an improvement of the intensity and contrast of the latent electrostatic image formed on the dielectric surface.
