Abstract
PURPOSE: To obtain the copied matter of high quality by letting the magnetic brush composed of the one component magnetic toners charged to the polarity opposite from that of an electrostatic latent image, thence the magnetic brush charged to the same polarity, make contact with the electrostatic latent image subsequently.
CONSTITUTION: A photosensitive drum 7 rotates in the arrow direction and has a negatively charged photoreceptor on its surface. The photoreceptor 7 is evenyl charged by a charged 8, is radiated with a light image by an exposure device and is developed by a device 10. The developing device 10 consists of a stationary magnt 12, sleeve 11 and hopper 13. The sleeve rotates in the counterclockwise direction and is held applied with negative developing bias voltage. One component magnetic toners TM are contained in he hopper 13 and the side wall of the outlet of the hopper 13 is applied with the voltage of the polarity opposite from that of the electrostatic latent image by a charge injection electrode 15. The image developed by the 1st device 10 is developed by the 2nd developing device 17 but at this time, the voltage opposite from that on the 1st device 10 is applied to the sleeve 18 and charge injection electrode 21.
