ABSTRACT:
A toner dispensing apparatus for electrophotographic copiers. The apparatus includes a toner dispenser portion positioned within the developer housing of the copier, and a toner supply portion positioned exteriorly of the developer housing. The two portions are detachably secured to one another such that when the supply of toner in the toner supply portion becomes exhausted, that portion may be replaced in its entirety. Both portions are provided with a novel valve means to permit transfer of toner from the supply portion to the dispenser portion in normal operation and to prevent toner spillage from either portion when separated. Additionally, a novel toner agitator structure is provided in the toner supply portion to ensure a smooth flow of toner therefrom. This structure includes a plastic bag for holding the supply of toner together with means for periodically deflecting the walls of the bag to loosen up the toner therein.
