    摘要: A Liquid ejecting method for ejecting liquid using a bubble, includes using a liquid ejecting head having an ejection outlet for ejecting the liquid, a bubble generating region where a bubble is generated in the liquid, a movable member which is disposed faced to the bubble generating region, and which is displaceable between a first position and a second position farther from the bubble generating region than the first position and which has a free end at a downstream side thereof; displacing the movable member from the first position to the second position by pressure based on generation of the bubble in the bubble generating region, wherein the bubble expands more to the downstream side than to the upstream side with respect to a direction toward the ejection outlet by the displacement of the movable member, thus directing the bubble toward the ejection outlet to eject the liquid through the ejection outlet; and imparting an operation to the liquid ejecting head to normalize a state of the liquid in a liquid flow path for the liquid at least before liquid ejection start or at the time of non-ejection of the liquid.

    摘要: A liquid discharge head comprises discharge ports for discharging the liquid, a bubble producing area for producing an air bubble in the liquid of liquid flow channels, and a movable member, which is disposed toward the bubble producing area, and displaceable between a first position and a second position farther away from the bubble producing area than the first position, the liquid discharge head discharging the liquid in such a manner that the movable member is displaced from the first position to the second position by a pressure due to a bubble produced in the bubble producing area, and the bubble is more greatly expanded downstream than upstream in a direction toward the discharge port, due to the displacement of the movable member. The head has a check valve disposed in a liquid supply passage leading to the liquid flow channels.

    摘要: A substrate, for use in a liquid discharge head for discharging liquid by applying thermal energy thereto, is provided with a heat generating member for applying the thermal energy to the liquid and a movable member so positioned as to be opposed to the heat generating member, to be fixed at the upstream side in the flowing direction of the liquid and to have a free end at the downstream end. Two wiring layers for applying a voltage to the heat generating member are provided in a superposed manner with an interlayer insulation layer therebetween and are mutually connected electrically via a through-hole. The through-hole is provided in a position different from the boundary between a fixing portion and a movable portion of the movable member.
