Abstract
An ink tank for an ink jet printer is provided. The ink tank includes a tank body, a sponge disposed in the tank body, for absorbing and storing ink, an air flow member positioned above the sponge, for guiding air outside the ink tank to be induced into the ink tank, a nozzle coupled to one end of the air flow member, for supplying air outside the ink tank to the ink tank, and an air flow hole formed at one side of the tank body connected to the other end of the air flow member, and opened/closed by a sealing means installed on a printer frame according to the movement of the carrier and the ink tank. The air outside the ink tank is supplied only during the printing operation, thereby preventing evaporation of moisture contained in the ink stored in the ink tank. Also, the internal pressure of the ink tank is adjusted to be lower than the atmospheric pressure, thereby preventing leaking of ink.
