摘要

A contact angle of water on the surface of a charging roller is equal to or smaller than a contact angle of water on the surface of the photo conductor. This structure prevents slip of the charging roller in an image forming apparatus wherein the charging roller is rotated due to the driving force of the photo conductor which is transmitted from the photo conductor as the charging roller comes in contact with the surface of the photo conductor.
