ELECTROPHOTOGRAPHIC METHOD AND DEVICE

PURPOSE: To provide an electrophotographic method and device which can generate a vivid image without ghost even when a high speed processing is adopted. CONSTITUTION: A voltage is impressed on a photoreceptor on such a charging system that a DC current is superposed on an AC current using a contact type charging member, and the surface of the photoreceptor is cleaned using a cleaning blade, wherein the rotating speed of the photoreceptor is over 50mm/sec. In this electrophotographic process, the element has an electric charge generating layer and an electric charge conveying layer, wherein the electric charge generating layer contains oxytitanium-phthalocyanine and azo-pigment, and the charging time B using DC current solely ranges between 0.1A and 0.5A, where A represents the total charging time required to make printing of one sheet.
