TONER CARTRIDGE, WHICH HAS THE WAY OF SHUTTERING Russian patent published in 2017 - IPC G03G15/08 

FIELD: printing industry.

SUBSTANCE: claimed group of inventions includes variants of a toner cartridge. The claimed toner cartridge, intended for use with the developing unit of image forming device, comprises: a housing having a front side, a rear side, an upper side, and a lower side. Housing has a toner holding tank, an outlet opening on the front side of housing for discharging the toner from toner cartridge, and an element for contact interaction having a first contacting surface and a second contacting surface. First contacting surface is located near the rear side of housing and is arranged to sense the force exerted from the rear side of housing fromactuating member of image forming device when the toner cartridge is mounted in image forming device and the second contacting surface is located near the front side of housing below the outlet opening. Element for contact interaction is configured to move from the first position to the second position while perceiving the force exerted. When the element for contact interaction is moved from the first position to the second position, the second surface of contact interaction is moved from rear side to front side of housing and protrudes from the front of housing without obstruction in front of the second surface of contact interaction for forced opening - in the direction from rear side to front side of housing - of shutter at the inlet opening of developing unit when toner cartridge is mounted in image formation device and is associated with developing unit.

EFFECT: prevents leakage of toner between the toner cartridge outlet opening and the developing unit inlet opening.
