PURPOSE: An automatic toner re-filler for a cartridge is provided to enable a user to charge a toner conveniently by automatically charging the toner without separating a cartridge from a body of a copy machine. CONSTITUTION: In order to enable a toner to slide into a toner cartridge(157), an air compression pump(101) generates compression air, and a first connection hose(143) connects a pressure sensor(119) to a toner refill storage tank(127). A second connection hose(151) connects the pressure sensor to the air compression pump, and a third connection hose(135) connects the toner refill storage tank to the toner cartridge. A control unit(105) controls the air compression pump according to the pressure of the pressure sensor.
