Abstract
PURPOSE: To enable the method to be practicably adapted even to a powder image transfer type electrophotographic copier by mixing conductive magnetic particles to the magnetic toner being conductor and having a high resistance value.
CONSTITUTION: The developer D comprising mixing conductive magnetic particles such as of iron balls of particle sizes 20 to 150μ and magnetic toner Db being conductor and of volume resistance value 1013Ωcm or over is adsorbed in brush form on the outside peripheral surface of a developing sleeve 3 by the magnetic force of a magnet roller 4. As the roller 4 rotates in the arrow B direction, the developer is conveyed in the arrow C direction and makes slide contacts to the surface of an electrophotographic photoreceptor 1 which is rotating in the arrow A direction, whereby the toner powder images 8 developed of electrostatic latent images are formed. At this time, the developer D is stirred by the magnetic material fine wires 6, 7 secured over the axial direction of the sleeve 4. The toner Db consumed in the developer D is automatically replenished from a developer replenishing tank 2 and the amount of the developer being conveyed to the developing part is defined by an ear height defining plate 5.
