DEVELOPER SUPPLY CONTAINER AND DEVELOPER SUPPLY SYSTEM Russian patent published in 2017 - IPC G03G15/08 

FIELD: manufacturing technology.

SUBSTANCE: present invention relates to developer supply container, which is detachably installed in developer filling device, and to developer supply system including them. Declared group of inventions comprises developer supply system and developer supply container. At that, developer supply container includes developer holding part, made with possibility of developer holding, outlet opening, made and arranged so, that to allow developer discharge in said developer holding part, wherein outlet hole has area not greater than 12.6 mm², drive force receiving part, made and arranged with possibility to receive driving force, and pump part made and arranged with possibility to act on above mentioned developer holding part with driving force received by above mentioned part for receiving driving force, for alternating change of said developer holding part internal pressure between pressure, much lower, than ambient environment pressure, and pressure, much higher than ambient environment pressure, for discharge of developer through said outlet hole.

EFFECT: technical result consists in provision of developer supply container and developer supply system, in which developer supply container internal pressure is negative, so that developer in developer supply container is appropriately loosening.
