PROBLEM TO BE SOLVED: To extremely heighten discharging efficiency and discharging force by controlling generated bubbles so as to effectively act to a movable member by a method wherein this liquid discharging method has a bubble generating process, during which the predetermined number of bubbles are generated anew in a bubble generating region for discharging liquid under the state that displacement is still present, and the like. SOLUTION: A movable member 31 has its fulcrum on the upstream side of a large flow, which runs by means of the discharging action of flow from a common fluid chamber 13 through the movable member 31 to a discharging port 18 side. When heat is generated with a heating body 2, the heat is applied to the liquid in a bubble generating region 11 locating between the movable member 31 and the heating body 2 so as to generate bubbles in the liquid on the basis of film boiling phenomenon. The pressure and bubbles on the basis of the generation of the bubbles preferentially act on the movable member 31 so as to deform the movable member 31 in order to open it about the fulcrum 33. By means of the displacement or displaced state of the movable member 3, the propagation of the pressure on the basis of the generation of the bubbles and the growth of the bubbles themselves are guided to the discharging port side. In addition, there is no limitation in the kind, shape and arrangement of the heating body 2 and the movable member 31. |
