方式用クリーニング装置。[Claim for Utility Model Registration] Since the developer of electrophotographic printers, copiers, etc. is highly magnetic toner and carries an electric charge, magrolls, DC bias power supplies, and In a cleaning device equipped with a blade for discharging toner, the DC bias power source (variable) is applied between the mag roll and the photoconductor to adjust the charge and effective polarity of the residual toner, and the toner on the sleeve on the surface of the mag roll is removed. A cleaning device for electrophotography, characterized in that the cleaning device for electrophotography is configured to discharge toner using the blade and collect residual toner without contacting the surface of the photoreceptor drum.
