PURPOSE:To surely recover without any toner sticking by recovering the toner scraped off by a toner scraping member with pressure and suction force of air flown through a duct. CONSTITUTION:The toner 1 is scraped off by the toner scraping member 12 after being passed between a 'mylar' 10 and a photosensitive body 5, is dropped to the vicinity of a sunctioning opening 11b, is forcedly pushed in the direction of the sucking opening 11b by air blown out in the direction of the arrow F from the blowing out opening 11a, and is recovered in the direction of an arrow G. The toner 1 sucked in from the suction port 11b is carried to a tank passed through the duct 11 in the direction of the arrow I, and since there is no part causing any mechanical abrasion inside the duct 11, no sticking of the toner is generated in the duct 11. Thus, recovery can be carried out without any toner sticking. |
