Abstract

A liquid ejecting head capable of ejecting liquids in different conditions includes an ejection outlet for ejecting a liquid; a liquid flow path for supplying the liquid to the ejection outlet, the liquid flow path having bubble generation heat elements used to eject the liquid and capable of selectively generating bubbles having different sizes; and a movable mechanism having at least one movable member arranged to face a bubble generation region formed in the liquid flow path by the bubble generation heat elements. The movable member has a free end on a downstream side with respect to a direction of the ejection outlet and a supporting member on an upstream side. The movable member is displaced in a direction to separate from the bubble generation region in accordance with a bubble generated by the bubble generation heat elements.
