Abstract
An ink cartridge for an ink jet printer includes an ink storing portion for containing ink and a head for ejecting droplets of the ink stored in the ink storing portion. The ink storing portion includes a chamber filed with ink in a liquid state, a negative pressure maintaining apparatus for maintaining the pressure of the inside of the chamber to be negative, and a uniform supply guide apparatus, installed between the chamber and the head, for guiding the ink in the chamber to be uniformly supplied to the head. Thus, since the ink is used by being stored in a liquid state, most of the amount of the stored ink can be used for printing, so that the efficiency in use can be improved much.
