PURPOSE: An auto cartridge color toner charging apparatus is provided to automatically charge insufficient color toner without the separation of a cartridge. CONSTITUTION: Four color toner refill storage tanks(127,129,131,133) store each color toner. An air compression pump(101) creates compressed air. A compressed air distributor(109) supplies the compressed air to the color toner refill storage tank. Four compressed air control valves(111,113,115,117) control the flow of the compressed air. A controller(105) measures the pressure of pressure sensors(119,121,123,125). The controller controls the air compression pump and the compressed air control valve.
