摘要：
The driving signal includes a first element that pressurizes the pressure chamber and that makes the liquid in the nozzle protrude to form a liquid pillar, and a second element that pressurizes the pressure chamber after the first element and that makes a portion of a liquid surface of the liquid, the portion being other than a surface of the liquid pillar, protrude from a position where the liquid surface in the nozzle is in contact with an inner surface of the nozzle, in a direction in which the liquid pillar protrudes, in a state where the liquid pillar has not yet separated from the liquid in the nozzle.
