ABSTRACT:
An ink cartridge and an inkjet printer using the same. The ink cartridge includes a cartridge case having an ink storing space, negative pressure forming foam inserted into the cartridge case, and a filter pipe installed on a bottom surface of the cartridge case, wherein the bottom surface of the cartridge case is formed to be entirely in contact with a bottom surface of the foam. Thus, a dead space around the filter pipe is minimized or eliminated, therefore solving a problem where the ink would otherwise remain to a certain extent in the dead space. In addition, the air existing in the dead space together with the ink does not affect the ink ejection performance of a head due to expansion and shrinkage of the air to stably maintain the ink ejection performance.
