<p>An ink jet recording head (8) comprises two common ink chambers (26, 27) communicating with both sides of a pressure generating chamber (24), and ink supply ports (30, 31), through which ink flows into the respective common ink chambers (26, 27) from the outside. One of the ink supply ports (30) is connected to a subtank (10), and the other of the ink supply ports (31) is connected to an ink cartridge (6) so that ink is replenished to the subtank (10) via the ink jet type recording head (8). Since ink is caused by head to flow backward into the ink cartridge (6) via the recording head (8) from the subtank (10), ink within the recording head can be forcedly circulated without complicating an arrangement of flow passages.</p> |
