A liquid ejecting method for ejecting liquid by generation of a bubble includes preparing a head comprising an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position; displacing the movable member 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; and wherein the displacing step including: first bubble generation step of displacing a free end side of the movable member by pressure produced by generation of a bubble in the bubble generating region; and second bubble generation step of generating at least one other bubble in the bubble generating region to eject the liquid through the ejection outlet.

[ What is claimed is:] [1.] A liquid ejecting method for ejecting a liquid by generation of a bubble, comprising the steps of:preparing a head having an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to said bubble generation region and displaceable between a first position and a second position further from said bubble generation region than the first position;displacing the movable member from said first position to said second position by pressure produced by the generation of the bubble in said bubble generating portion to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side;wherein said displacing step comprises a first bubble generation step of displacing a free end side of said movable member by pressure produced by generation of a bubble in said bubble generating region and a second bubble generation step of generating at least one other bubble in said bubble generating region, while said movable member is located at a displaced position by said first bubble generating step, to eject the liquid through the ejection outlet,wherein said first bubble generation step displaces the movable member without electing the liquid through the ejection outlet, and said second bubble generation step elects the liquid through the ejection outlet.
