ABSTRACT:
A method and an apparatus for forming an electrophotographic image based on applying an AC voltage or a voltage obtained by superposing a DC voltage on an AC voltage to an electroconductive base of a sensitive medium having a photoconductive layer formed on the electroconductive base, bringing a grounded electroconductive or semi-electroconductive member into contact with or close to the surface of the sensitive medium to charge this surface to a predetermined polarity, and exposing the surface of the sensitive medium to an image to form an electrostatic image.
