DEVELOPER SUPPLY CONTAINER AND DEVELOPER SUPPLYING SYSTEM Russian patent published in 2014 - IPC G03G15/08 

FIELD: physics, photography.

SUBSTANCE: invention relates to a developer supply container detachably mountable to a developer filling apparatus, and to a developer supplying system including same. The developer supply container and developer supplying system are used with an image forming apparatus, such as a copying machine, a fax machine, a printer or a complex device having functions of a plurality of such devices. The disclosed group of inventions includes a developer supply container detachably mountable to a developer filling apparatus, and a developer supplying system. The container comprises a chamber for holding developer; a supply part for supplying developer into the chamber during rotation thereof; a chamber for discharging developer which is provided with an outlet opening for discharging developer supplied by the supply part; a part for receiving a drive force for receiving a rotary force for rotating the supply part from the developer filling device; a pumping part for acting on at least the chamber for discharging developer, wherein the pumping part has a volume which varies during back and forth movement; an a drive conversion part for converting the rotary force received by the part for receiving the drive force into a force for operating the pumping part.

EFFECT: improved interaction of the supply and pumping part of the developer supply container, wherein two drive parts of the developer supply container properly enter into a drive connection with two output drive parts of the side of the image forming apparatus, respectively, and providing a system wherein a developer supply container receives a back and forth force from the developer filling device corresponding to the drive of the pumping part.
