Ink cartridge
The present invention provides an ink cartridge including a cartridge body defining an air vent at an upper section thereof and an ink discharge port detachably assembled to a lower section of the cartridge body. The cartridge body and/or the ink discharge port can be replaced separately when they are damaged and, thus, there is no need to replace the ink cartridge as whole.
