摘要： A charging method in which the surface of an image bearing device is charged in two steps in contact with the surface of the image bearing device before a latent image is formed on the surface of the image bearing device, the contact charging method includes two steps. First, the surface of the image bearing device is charged with a contact charging device which applies a voltage consisting of an AC component and a DC component superposed on the AC component. Second, the surface of the image bearing device is charged by a contact charging device applied with such a DC voltage as to discharge at least part of a pattern of charge potential variation of which the pitch corresponds to the frequency pitch of the AC component, which is caused in the primary charging operation.
