摘要： An ink jet recording head is provided with one heat generating member in each of ink flow paths, and the discharge port thereof is arranged on the extended line extending in the normal direction from the center of the main surface of the heat generating member to the surface of the substrate. Then, on the surface of the substrate, non-bubbling area is provided on the center within the projected area having the discharge port projected thereon. Bubble brought to the boil by the heat generating member pushes out ink from the discharge port by the pressure exerted by the bubble, while being communicated with the outside. With the structure thus arranged, it is made possible to enhance the precision of discharge direction of the liquid droplet discharged from the discharge port.

摘要： In an ink jet recording head from which a small ink droplet and a large ink droplet can be discharged, a common liquid chamber is connected to discharge ports via ink flow paths and pressure chambers, and ink droplets are discharged from the discharge ports by utilizing thermal energy of heaters. Widths of the ink flow paths are narrower than widths of the pressure chambers so that the ink flow paths act as restriction portions. If it is assumed that a sectional area of the small liquid droplet ink flow path is SS, a sectional area of the small liquid droplet pressure chamber is SRS, a sectional area of the large liquid droplet ink flow path is SL and a sectional area of the large liquid droplet pressure chamber is SRL, a relationship SS/SRS

摘要： A container for containing liquid to be ejected. The container includes a negative pressure producing member accommodating chamber for accommodating a negative pressure producing member. The negative pressure producing member accommodating chamber is provided with an air vent for fluid communication with ambience and a liquid supply portion for supplying the liquid to a liquid ejecting head having ejection outlets. The container also includes a liquid containing chamber which is substantially hermetically sealed except for a fluid communication path through which the liquid containing chamber is in fluid communication with the negative pressure producing member accommodating chamber. A partition is provided for separating the negative pressure producing member accommodating chamber and the liquid containing chamber. The partition is provided with an ambience introduction path for introducing the ambience into the liquid containing chamber from the negative pressure producing member accommodating chamber. The ambience introduction path forms a capillary force generating portion. The capillary force which is produced by the capillary force generating portion satisfies a relationship between that capillary force and potential head differences, head losses, and other capillary forces in the container.
