Abstract
An ink jet printer of the invention is comprised of: an ink cartridge including an ink pack enclosing an ink and an air injection pack arranged adjacent to the ink pack; and an air feed unit for feeding the air to the inside of the air injection pack on the basis of the control of a controller. When the air is injected from the air feed unit into the air injection pack, the volume of the ink pack is decreased so that the ink is discharged from the ink pack, as the volume of the air injection pack is increased. And, the ink, as discharged from the ink pack, is fed to a printing head so that it is discharged to a paper.
