Abstract

PURPOSE:To suppress the sticking of toner on the outer periphery of a developing sleeve by arranging a magnet 4 at the inner periphery of the developing sleeve nearby the position opposite to a developer scraping plate. CONSTITUTION:The developer 9 consisting of two components, i.e. toner and carriers, napped nearby the part opposite to the magnet 4 contacts the outer periphery of a photosensitive drum 1 to perform development. As the developing sleeve 2 rotates as shown by an arrow B, the developer 9 is napped at the part opposite to the magnet 5, then the napping is eliminated, and its conveyance is further carried on. The carriers are attracted to the magnet 11 as they approach the magnet 11, so they move onto the magnet 11 while sliding on the outer periphery of the sleeve 2, and are napped 12. At this time, the carriers strike toner which sticks on the outer periphery of the sleeve 2 yet and toner which is to stick, so the toner is prevented from sticking the outer periphery of the sleeve 2. Then the carriers and toner are scraped off by the developer scraping plate 8. Consequently, no toner sticks and is deposited on the surface of the sleeve 2 even after long-period use.
