Abstract
A method for filling toner into a toner cartridge includes the steps of (a) taking a container, which accommodates the toner therein and has opposite first and second ends, and then forming a toner outlet at the first end, (b) sleeving the toner cartridge, which is provided at an end thereof with an opening, onto the container from the first end to the second end via the opening, (c) forming an air permeable hole at the second end, (d) withdrawing the container from the toner cartridge to enable the toner to leave the container via the toner outlet and stay inside the toner cartridge, and (e) sealing the opening of the toner cartridge by a cover. The method is simple and convenient to operate. With the method, the toner can be effectively filled without leakage and with reduced amount of residual toner.
