Abstract: A cartridge 1 is provided with an ink pack 9, an air bag 10 capable of abutting the ink pack 9, and a pressurizing chamber 11 that stores the ink pack 9 and the air bag 10. In the case where the amount of ink in the ink pack 9 decreases, pressurized air is introduced into the air bag 10, the ink pack 9 is pressed against the air bag 10, and thereby the internal pressure of the ink pack 9 is increased. After that, pressurized air is introduced into the pressurizing chamber 11 so as to increase the internal pressure of the pressurizing chamber 11 and pressurize the ink pack 9 from outside. Accordingly, the ink in the ink pack 9 is supplied from an ink supply port 12 to the inkjet printer 2.
