ABSTRACT:
An ink-jet recording apparatus comprising an ink-discharging opening coupled to an ink chamber for discharging ink therefrom toward a recording sheet. The ink-discharging opening is formed at a center and bottom of a concave portion formed in a thin plate made of an insulating material. A first electrode is provided on one surface of the thin plate and around the concave portion and a second electrode is provided on the other surface of the thin plate and at the vicinity of the ink-discharging opening, the first and second electrodes being electrically coupled to an ink-discharging control signal source. This arrangement can omit an air supply system to simplify the structure of the recording apparatus.
