An ink filling apparatus for an ink cartridge disclosed in the present invention comprises an ink storage unit which stores ink to fill an ink cartridge; an air supply unit which selectively supplies air to the ink cartridge; and a charging unit where the ink cartridge is selectively mounted and which supplies the air in the air supply unit to the ink cartridge in order to generate negative pressure inside the ink cartridge to fill the ink cartridge with the ink in the ink storage unit. According to the composition above, the efficiency of filling can be improved by conveniently filling an ink cartridge with ink using negative pressure. |
