PURPOSE:To simplify the mechanism of a toner recovery/reusing device and to improve the performance of the titled device by individually removing positively charged toner, paper powder and negatively charged toner and reusing only the positively charged toner. CONSTITUTION:Only the positively charged toner out of the toner and paper powder adhered to the surface of a photosensitive body 1 is adsorbed by the 1st cleaning brush 5 and removed from the body 1. The toner adsorbed by the 1st cleaning brush 5 is adsorbed by a dittoing roll 9, removed from the brush 5, scraped by a scraper 10, and then carried to a developing device by a carrying means 11 so as to be reused. On the other hand, the negatively charged toner and paper powder which can not be removed by the brush 5 are removed by the 2nd cleaning brush 6, carried through a dittoing roll 16, a scraper 19 and a carrying means and removed. |
