摘要:
A liquid ejecting method for ejecting a liquid comprises using a liquid ejecting head having an ejection outlet portion having an ejection outlet for ejecting the liquid, a liquid flow path in fluid communication with the ejection outlet portion, a bubble generation region for generating a bubble in the liquid, and a movable member disposed to face the bubble generation region and provided with a free end closer to the ejection outlet portion than a fulcrum portion thereof, and displacing the movable member by a pressure based on generation of the bubble from a position of a reference surface to a position of a maximum displacement, thereby ejecting the liquid, wherein a relation of 2.theta..sub.E -7.degree..ltoreq..theta..sub.M .ltoreq.2.theta..sub.E +7.degree. is satisfied where, with a reference of the reference surface, .theta..sub.M is an angle of the movable member at the maximum displacement thereof about the fulcrum portion and .theta..sub.E is an angle of an axis connecting the fulcrum portion with an intersecting point of a center axis of the ejection outlet with a connecting surface of the ejection outlet portion to the liquid flow path, and wherein .theta..sub.M is an acute angle.
