Toner recycling system for copier and facsimile printer

摘要

A toner recycling system (6) removes toner using a scraper blade (6a) from the photo sensitive body (1) to prepare this for the next image production process. The toner recovered is delivered using a screw conveyor, to a developer stirrer and conveyor belt of the stirrer and conveyor part. The recovered toner is conveyed to a further refilling part of the toner conveyor line lying above. The conveying speed of the toner conveying part is adjusted so that it is higher than that of the developer stirring and conveying part. The developer stirring and conveying part stirs the developer and delivers the recovered toner to a developer carrier. The developer which is arranged at the lowest flow side of the developer stirring and conveying part, is delivered to the toner refilling part of the toner conveyor line, lying further down, so that the developer is turned over.
