Abstract

PURPOSE:To clean an image carrier easily and completely without the generation of fog by arraying plural magnet brush forming means along the moving direction of the image carrier and cleaning the surface of the image carrier to which remaining developing agents are adhered successively by the plural magnet brushes. CONSTITUTION:Magnetic sources 5, 6 are installed in nonmagnetic cylindrical sleeves 3, 4. The magnetic source 5, 6 have plural magnets 51-54 and 61-63, respectively. Prescribed voltage is applied to respective sleeves 3, 4 by voltage applying means E1, E2. The voltage applying means E1, E2 apply electric potential with polarity reverse to the charge polarity of a removed developing agent or the earth potential to the surface of each sleeve. Scrapers 7, 8 scrape removed toner from the surfaces of sleeves 3, 4. The removed developing agent is discharged from a discharging part 10.
