An ink jet printer has an ink circulation unit including an image recording unit to discharge ink to perform image recording on a recording medium; a first tank disposed above the image recording unit in a gravitational force direction to supply the ink to the image recording unit through a first ink path; a second tank disposed below the image recording unit in the gravitational force direction to collect the ink that was not discharged from the image recording unit through the second ink path; a pump to send the ink from the second tank to the first tank through a third ink path, and at least a part of the first ink path connecting the first tank and the image recording unit is positioned below an ink liquid level in the second tank in the gravitational force direction.
