Abstract
PURPOSE: To obtain always clear copy images, by providing a magnetism generating means inside a toner holding member of which surface is coated with specified copolymer, and developing an electric latent image by holding the magnetic toner on the holding member surface.
CONSTITUTION: A magnet 7a is provided inside a toner holding member 7 having coating 7b of vinyl pyridine base polymer (preferably polymer or copolymer of 4- vinyl pyridine, 2-vinyl pyridine, etc.) on the surface of conductive cylindrical rotating body, and this member 7 is disposed in a developing device 4 holding a magnetic toner 5. By exposing an image to a photosensitive drum for charging 1 which rotates in the direction of the arrow by means of an optical means 3, and electrostatic latent image is formed, and this latent image is developed by the magnetic toner 5 held on the holding member 7 which rotates in the direction of the arrow. The obtained developed image is transferred on an ordinary paper 10 in a transfer part 9, and a copy is obtained by fixing with heat or pressure.
