ABSTRACT:
Disclosed is the ink jet head in which a part of the partition wall of the ink manifold 8 is constructed from the flexible damper membrane 9 which absorbs the pressure wave of the ink by being vibrated therethrough, the damper membrane 9 entirely vibrating under the single vibration mode with the same phase and having the natural frequency so as not to produce resonance with the reflected wave, thereby it can avoid that ink ejecting property is influenced by reflection occurring in the retrograde component of the pressure wave and it can obtain uniform ink ejecting property every ejecting time.
