<p>An ink jet apparatus includes a plurality of ink chambers (4) each having a front end and a rear end, a manifold (18) provided to introduce ink into each ink chamber (4) with a front side surface on a side near the front end of each ink chamber (4), and a nozzle provided at the front end of each ink chamber (4). Ink is jetted from the nozzle by applying pressure to the ink contained in each ink chamber (14). Each of the ink chambers (4) has a cross-sectional area (S2) and the manifold has a cross-sectional area (S1), the cross-sectional area (S1) of the manifold (18) being at least 0.5 times the cross-sectional area (SA) of all the ink chambers combined.</p> |
