An ink jet printer as an liquid ejection apparatus includes two ink channels which are independent from each other and communicate an ink tank and a pressure chamber communicating with a nozzle, a pump pressurizing ink in one of the ink channels, and a mode switching section capable of switching between two modes of ink ejection mode and ink circulation mode. In the ink ejection mode, ink is provided from the ink tank to the pressure chamber to the pressure chamber through the two ink channels, so that the ink is ejected through the nozzle. In the ink circulation mode, the pump pressurizes ink in one of the ink channels, so that the ink is forcibly circulated between the ink tank and the pressure chamber. The liquid ejection apparatus is capable of reliably discharging air bubbles remaining in the ink by ejecting a minimum amount of liquid through the nozzle.
