Liquid ejection head and apparatus and liquid ejection method

摘要

A liquid ejecting head having at least two liquid ejecting head portions, the liquid ejecting head portions each includes a plurality of ejection outlets for ejecting liquid; a plurality of bubble generating regions for generating bubbles in the liquid; and a plurality of movable members each of which is displaceable between a first position and a second position farther from the bubble generating region than the first position; wherein the movable member is displaced from the first position to the second position by pressure produced by the generation of the bubble in the bubble generating portion to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side; an amount of ejection is controlled beforehand by changing at least one of: at least one of a dimension and a position of energy generating means for generating the bubble; at least one of a dimension and a position of the movable member; a dimension of the ejection outlet; at least one of a dimension and a configuration of a structure of a path along which the liquid flows. <IMAGE>
