Abstract
PURPOSE:To maintain a single or double color image quality always stable by containing residual toners on a photoreceptor in separate container in black and red copying or single black copying, and by recirculating only black toner for reuse. CONSTITUTION:Black toner container 19 and red and black toners container 25 are installed in cleaner chamber 18 on both sides of cleaning fur brush 17, and in the outlets of these containers 19 and 25, black toner cleaning plate 23 and red and black toners cleaning plates 24 are pivotally mounted on shafts 26 and 27, respectively, each opening and closing with solenoids 21 and 22, and contacting to fur brush 17 in each opening position to scrape off the attached toners and store them in each container 19 and 25, and contacting to cleaner chamber 18 in each closing position to tightly close each container. In addition, suction opening 20 is provided in container 19 to draw the stored toner in container 19 at a proper time, and to return it to feed hopper 11 of black toner developing device 10 for reuse.
