Abstract
A liquid ejecting method using a liquid ejection head having a movable member disposed faced to a bubble generating region and having a free end at a downstream side thereof with respect to a flow direction of liquid, wherein the free end of the movable member is displaced by a pressure generated by a bubble in the bubble generating region, and the pressure is directed toward an ejection outlet by the movable member to eject the liquid through the ejection outlet, the improvement residing in that: the free end of the movable member providing a substantially harmetically sealed state for the bubble generating region, is displaced so as to guide a pressure wave resulting from the bubble formation toward the ejection outlet while non-contact state is substantially maintained between the movable member and the bubble.
