ABSTRACT:
A liquid discharging method of regulating and directing an air bubble to a discharge port by a substrate having a heat generating surface for generating heat for creating an air bubble in a liquid disposed in face-to-face relationship with a liquid discharge port, a movable member provided so as to intervene between the heat generating surface and the discharge port, and having a free end displaceable by the air bubble, the free end or a changing portion being located in an area opposed to the minimum area region of the discharge port or upstream of the opposed area, and an opposed surface opposed to a surface which provides the heat generating surface side of the movable member when the free end of the movable member is displaced by the air bubble, and fixed to cooperate with the movable member during the displacement of the movable member to direct the air bubble toward the discharge port.
