IPC: G03G21/00
Filed: 1987-05-18
Abstract: PURPOSE:To easily remove toner by positively electrifying toner which is stuck to a photosensitive body after transfer, by corona discharge and attracting toner by a cleaning carrier having the opposite polarity. CONSTITUTION:A photosensitive body 1 is negatively electrified and toner T having the positive polarity remains on the photosensitive body 1. Corona discharge is caused by a precleaning charger 2 to positively electrify toner T more intensively, and the negative electrified surface of the photosensitive body 1 is positively electrified. A cleaning sleeve 3 is arranged, and a cleaning carrier C is held as a magnetic brush without applying a bias voltage. This carrier C is negatively electrified by electrification due to friction to toner T and at tracts toner T to remove toner T from the photosensitive body 1. Thereafter, toner T is recovered by a toner recovery roll 8. Consequently, a bias power source is unnecessary and cleaning is satisfactorily performed because toner is positively electrified intensively by the precleaning charger.
