ABSTRACT:
A Liquid ejecting method for ejecting liquid using a bubble, includes using a liquid ejecting head having an ejection outlet for ejecting the liquid, a bubble generating region where a bubble is generated in the liquid, a movable member which is disposed faced to the bubble generating region, and which is displaceable between a first position and a second position farther from the bubble generating region than the first position and which has a free end at a downstream side thereof; displacing the movable member from the first position to the second position by pressure based on generation of the bubble in the bubble generating region, wherein the bubble expands more to the downstream side than to the upstream side with respect to a direction toward the ejection outlet by the displacement of the movable member, thus directing the bubble toward the ejection outlet to eject the liquid through the ejection outlet; and imparting an operation to the liquid ejecting head to normalize a state of the liquid in a liquid flow path for the liquid at least before liquid ejection start or at the time of non-ejection of the liquid.
