An ink cartridge for ink-jet printer where the ink cartridge comprises an ink supply adjusting valve, air vent valve, and ink storage chamber. Ink supply adjusting valve includes an ink inlet communicates in ink fluid communication with the ink storage chamber and an ink outlet connected with ink-supply port of ink storage chamber and a valve body constructed of a film and holder thereof and in which at least two small ink chambers are partitioned and both of the small ink chambers are communicated through a small ink channel. Air vent valve is a normal-closed one-way valve controlled by elastic valve cap under the level of ink fluid inside the ink storage chamber. Under static equilibrium during operation, suction of print head causes higher negative pressure inside the ink storage chamber and air vent valve is opened by atmosphere pressure, and ink flows into the ink supply adjusting valve.
