Abstract (en)

[origin: EP0774355A2] An ink jet apparatus includes a plurality of ink chambers each having a front end and a rear end, a manifold provided to introduce ink into each ink chamber with a front side surface on a side near the front end of each ink chamber, and a nozzle provided at the front end of each ink chamber. Ink is jetted from the nozzle by applying pressure to the ink contained in each ink chamber. A position of the manifold is such that a distance between the front side surface of the manifold and the rear end of each ink chamber is set to 0.2mm or more, and a distance between the front side surface of the manifold and the nozzle is set to 3mm or more. Accordingly, pressure necessary for jetting ink droplets can be maintained for a relatively long period of time. Therefore, the ink can be smoothly introduced from the manifold into each ink chamber, thereby improving print quality. <IMAGE>
