Abstract
This specification discloses an electrophotographic process for forming an electrostatic latent image on a photosensitive medium which may consist of an insulative layer and a photoconductive layer (and further an insulative layer), and also discloses an apparatus for carrying out the process. The electrophotographic process essentially comprises the primary charging step of uniformly charging the insulative layer of the photosensitive medium, and the step of contacting a liquid with said insulative layer and applying a desired voltage to the liquid to thereby discharge or charge the liquid and substantially simultaneously therewith, applying light from an object image to the photoconductive layer of the photosensitive medium. The process may further comprise other various steps as required in electrophotography, such as overall or blanket exposure, development, image transfer and cleaning of the photosensitive medium.
