<p>An electrophotographic method and an apparatus employed for effecting the method, in which a photoreceptor drum having a fixed magnet member in it is employed. After forming an electrostatic latent image on the surface of the photoreceptor drum, the photoreceptor surface is brought into contact with the magnetic developing material within a developing material hopper so as to attract the developing material onto the surface of the photoreceptor drum by magnetic force. When the photoreceptor surface further passes an electrode roller, the toner remains only at the image portion for development into a visible toner image. As a force for removing the magnetic developing material from the photoreceptor surface, a resultant force of a magnetic force connecting the photoreceptor drum and the electrode roller and an electrostatic force connecting the photoreceptor drum and the electrode roller, is employed. Thus, the present invention provides the novel electrophotographic method and the apparatus for executing the method, which is simple in construction and a compact in size, and capable of providing images with a high resolution. <IMAGE></p> |
