ABSTRACT:
A rotating sleeve-type magnetic brush cleaning apparatus removes residual toner from a peripheral surface of an image carrying member of an image former. The apparatus comprise a magnetic brush that includes electrically insulated magnetic particles provided on an outer surface of the rotating sleeve which sweep the peripheral surface of the image carrying member; and a voltage source for applying a superposed electric potential including a DC voltage component and an AC voltage component between the image carrying member and the magnetic brush. The magnetic brush is biased to a potential which is reverse in polarity to an electrification polarity of the toner by the DC potential.
