Abstract
In an electrophotographic process including an image forming process comprising a charging step of bringing a conductive charging member into contact with a surface of a photoreceptor and applying a superimposed voltage of a direct current voltage and an alternating current voltage to said conductive charging member to directly charge the surface of the photoreceptor, an image exposing step, and a developing step, the application of the voltage to said conductive charging member is stopped for every cycle of the image forming process, whereby the wear of the photoreceptive layer can be reduced and the life of the photoreceptor can be extremely improved.
