ABSTRACT:
An electrostatic image forming method, which uniformly charging the surface of an electrostatic image forming material comprising (1) surface portions each having an insulating surface and occupying the surface of an insulating support in a patternlike manner and (2) conductive layer portions each having a conductive surface and formed on the remaining areas of the surface of the insulating support in a manner that the conductive layer portions are electrically isolated from the earth: grounding the surfaces of the charged conductive layer portions to the earth so as to remove the charges from the charged conductive layer portions so that the charges in the surfaces of the insulating surface portions remain as the desired electrostatic image.
