Abstract
An electrophotographic imaging method comprises a first process for charging an electrically insulating layer formed on the surface of a photosensitive drum, and a second process for image-exposing the charged insulating layer to form an electrostatic latent image thereon. The first process includes a first step for bringing a pliable contactor having a specific electric resistance of 10.sup.8 .OMEGA..multidot.cm in contact with the insulating layer, and a second step for impressing a voltage on the contactor in contact with the insulating layer by means of an electrode having a specific resistance lower 10.sup.5 to 10.sup.7 .OMEGA..multidot.cm. Thus the insulating layer is charged.
