Abstract

PURPOSE:To remove the mixed toners in combination by once letting the toners scraped from a developing roller fall from the scraper plate to let them diffuse thence receiving the same on a separating roller or separating belt within the 2nd developing unit. CONSTITUTION:The black-color developer containing red-color toners scraped by a scraper plate 28 is so arranged as to fall from the terminal end of the scraper plate 28 onto the coil spring belt 45 which has been charged to the polarity opposite from the red-color toners. Since the coil spring belt 45 is opened with multiple gaps, the balck-color toners and their carriers fall downward through these gaps and the red-color toners are attracted by the belt 45 and are thereby conveyed. When the red-color toners are still contained in the developer having passed through the belt 45, the developer is stirred and flowed convectionally by an impeller 50, whereby they are attracted on the belt.
