摘要： A liquid discharging method which employs a liquid discharging head consisting of a liquid discharging port, a bubble generating region where the bubble generates in the liquid and a movable member that can move between a first position and a second position which is located at a point farther from the bubble generating region compared with the first position, wherein the movable member moves from the first position to the second position by the pressure of the bubble generated by the bubble generating energy in the bubble generating region, and at the same time the bubble expands farther toward the downstream direction compared with the upstream direction by the displacement of the movable member in order to discharge the liquid out of the liquid discharging port by the liquid discharging energy applied to such liquid. The movable member has its free end in the downstream side with respect to its fulcrum and the liquid is discharged by applying the discharging energy corresponding to a saturation domain where the amount of the liquid to be discharged out of the liquid discharging port is substantially saturated in accordance with the increase of the discharging energy.
