ABSTRACT:
An electrophotographic method, and an apparatus for performing the method, which is simple in construction, compact in size, and capable of providing images with a high resolution employs the use of a photoreceptor drum having a fixed magnet member therein. After forming an electrostatic latent image on the surface of the photoreceptor drum, the photoreceptor surface is placed in contact with 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. To remove the magnetic developing material from the photoreceptor surface, a magnetic force connecting the photoreceptor drum and the electrode roller and an electrostatic force connecting the photoreceptor drum and the electrode roller are employed.
