PURPOSE:To realize stable and excellent supply from a conveying body to a part to be developed by providing a voltage impressing means which separates toner and carriers and sticks the toner to the conveying body and a removing means which remove carriers from the conveying body. CONSTITUTION:An AC voltage from an AC power source 18 is impressed between a developing sleeve 11 and a photosensitive drum 1. Then, a scraper 19 is arranged at the exit side of the developing sleeve 11 between the developing sleeve 11 and an electrode holder 14 and carriers C in a developer G carried to the developing sleeve 11 are scraped. Those scraped carriers C are guided by a guide plate 20 and collected. Thus, the supply from the conveying body to the part to be developed is carried out stably and excellently. |
