PURPOSE: A toner automatic supply system of a laser printer cartridge using difference in air pressure capable of minimizing dust in a toner powder tube is provided to automatically control air valves using monitoring information by automatically monitoring toner amount in the laser printer cartridge. CONSTITUTION: A first toner hose(201) for inhaling toner from a toner powder tube(100) and a second toner hose(202) for discharging the toner from an automatic toner supplier(200) to a printer cartridge(300). An air pressure control unit(400) connects to an air pressure control unit(203) of the automatic toner supplier. The air pressure control unit controls the air pressure of the inside automatic toner supplier. A sensing sensor monitors the residual toner of the automatic toner supplier.
