摘要： A liquid ejecting head ejects liquid by generating a bubble. The head includes a first liquid flow path for direct fluid communication between a first common liquid chamber and an ejection outlet, a second liquid flow path having a heat generating element for applying heat to the liquid to generate a bubble in the liquid, and a supply path for supplying the liquid to above the heat generating element from an upstream side of the heat generating element in a direction along the heat generating element. A movable member is disposed between the first and second flow paths, faces the heat generating element, and is displaced to a side of the first liquid flow path because of pressure generated when the heat generating element is driven, and has a fulcrum and a free end located downstream of the fulcrum. A guide path is provided in which the liquid flows above the heat generating element in the second liquid flow path.

摘要： A liquid discharging method for discharging liquid, which uses the pressure exerted at the time of creating each of bubbles in liquid in a bubble generating area, is arranged to provide two bubble generating areas for generating bubbles in such a manner as to enable these areas to face each other at least partly, hence discharging liquid by means for the pressure thus exerted in the bubble generating areas. In this way, it becomes possible to increase the amount of liquid discharged, as well as to enhance the durability of the movable members, while stabilizing the discharge of liquid from each of the discharge openings.
