Abstract:
A liquid ejecting method for ejecting a liquid by generation of a bubble, comprising the steps of:preparing a head comprising an ejection outlet to which the liquid is supplied directly from a liquid chamber for ejecting the liquid, a heat generating element for generating heat to form the bubble, the heat generating element having a heat generating surface which is at least one of substantially flush with and smoothly continuous with a surface upstream from said heat generating surface, a bubble generation region at which is generated the bubble in the liquid, a movable member having a fulcrum and a free end located downstream of the fulcrum relative to a direction of flow of the liquid;generating a bubble by applying energy to the heat generating element;displacing from a first position to a second position the free end of said movable member by a pressure produced by generation of the bubble in said bubble generating region; andrestraining, with fluid communication maintained between the ejection outlet and the liquid chamber, the free end of said movable member from entering the bubble generation region beyond a first position which is taken by the free end of said movable member before generation of the bubble.
