Abstract:
A liquid ejecting method for ejecting a liquid using a bubble, comprising the steps of:providing a liquid ejecting head having an ejection outlet for ejecting the liquid, a heat generating element for generating heat to form the bubble, the heat generating element having an area, a bubble generating region where the bubble is generated in the liquid, and a movable member which is disposed faced to the bubble generating region and which has a fulcrum and a free end located downstream of the fulcrum relative to a direction of flow of the liquid, the movable member being displaceable between a first position and a second position farther from the bubble generating region than the first position, wherein a portion of the movable member facing a center point of the area of the heat generating element is displaceable; 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 a downstream side than to an 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 heating the liquid in a liquid flow path for the liquid through a supporting member for supporting the movable member to normalize an operational state of the movable member.
