Abstract

PURPOSE:To obtain sufficient cleanability for the toners on a photosensitive drum contg. the toner charged to a reverse polarity by applying AC voltage upon a non-magnetic sleeve as magnetic brush bias. CONSTITUTION:A carrier which charges positive with respect to a toner and a carrier which charges negative, for example, a carrier prepd. by coating iron powder with a ''Teflon '' resin or a carrier prepd. by coating the same with a styrene methacrylate resin, are mixed as a carrier for cleaning, and AC voltage of, for example, 0-200V effective voltages, is applied as magnetic brush bias VCL upon the non-magnetic sleeve of a magnetic brush roll 4. Thereby, the toners of both polarities are cleaned, and the copies of less background fogs are obtained.
