PROBLEM TO BE SOLVED: To provide an ink jet recording head capable of being subjected to highly reliable and certain emission restoring treatment without bringing about the size increase of the emission restoring treatment system of the ink jet recording head and the increase in cost accompanied by highly pressure-resistant planning or the like and an increase in operation cost, an ink jet recording apparatus using the same and an emission restoring method of the ink jet recording head. SOLUTION: A plurality of ink supply ports 18a, 18b are provided to an ink jet recording head to enable the individual connection of ink tanks 20a, 20b to the ink supply ports 18a, 18b and the introducing pressure of ink in the ink supply ports 18a, 18b is changed corresponding to the height of the liquid level of ink in the ink tanks 20a, 20b. |
