Abstract:
A liquid ejection head comprising:a heat generating surface for generating heat for generating a bubble in liquid, the heat generating surface being at least one of substantially flush with and smoothly continuous with an upstream surface of the heat generating surface, a portion above said upstream surface and a further upstream portion being in fluid communication with each other when said heat generating surface does not generate heat;a movable member having a free end and a fulcrum, the movable member and the heat generating surface having a space therebetween;an ejection outlet for ejecting the liquid using the generation of the bubble, the ejection outlet being opposed to the heat generating surface with the movable member interposed therebetween; andan opposing member cooperable with the movable member to direct the bubble toward the ejection outlet;wherein the movable member directs the growing bubble toward the ejection outlet in a direction substantially perpendicular to the heat generating surface.
