<p>PURPOSE:To obtain a good image by restraining residual potential of a photoreceptor layer, by exposing an image by using a photoreceptor in which an adhesive agent layer, an electric charge generating layer and an electric charge transporting layer are laminated on a conductive layer and by applying a developing bias in the presence of a developer. CONSTITUTION:An aqueous ammonia solution of casein is applied and dried on the Al surface of an Al laminated paper to obtain an adhesive agent layer and an ethanol solution of a mixture in which a disazo pigment and a PVB are mixed is applied and dried to obtain an electric charge generating layer. Then, a resin liquid contg. a positive hole transporting substance such as pyrene is applied and dired to obtain a function separating type photoreceptor having a laminated struture. The surface of the photoreceptor is uniformly negative- charged by corona discharging to expose an image. A developer incorporating a positive charged toner and iron powder is used for the low potential latent image and a developing bias having -150V is applied and a development is performed to fix. In such a way, an image without stain on the ground is obtained.</p> |
