摘要： A liquid discharge head comprises a separation member for separating the discharge liquid flow paths communicated with discharge ports for discharging discharge liquid to enable discharge liquid to flow, and the bubbling liquid flow paths to enable bubbling liquid to flow, which is provided with the bubble generating areas for creating bubbles used for discharging discharge liquid from the discharge ports. This separation member is provided with the opening portions positioned to face the bubble generating areas, and displacement members provided for the separation member corresponding to the openings, having the free ends to be displaced by bubbles created on the bubble generating areas provided for the separation member. Then, with no bubbles created on the bubble generating areas, the displacement members interrupt the opening portions, and with bubbles created thereon, the free ends of the displacement members are displaced to discharge discharge liquid from the discharge ports of the head. Hence, this head can prevent discharge liquid from entering around the heat generating members at the time of bubble disappearance, and the mixture of discharge liquid and bubbling liquid when the head is left intact for a long time, while maintaining the excellent discharge efficiency by means of the displacement members thus arranged.

摘要： A liquid discharging method which employs a liquid discharging head consisting of a liquid discharging port, a bubble generating region where the bubble generates in the liquid and a movable member that can move between a first position and a second position which is located at a point farther from the bubble generating region compared with the first position, wherein the movable member moves from the first position to the second position by the pressure of the bubble generated by the bubble generating energy in the bubble generating region, and at the same time the bubble expands farther toward the downstream direction compared with the upstream direction by the displacement of the movable member in order to discharge the liquid out of the liquid discharging port by the liquid discharging energy applied to such liquid. The movable member has its free end in the downstream side with respect to its fulcrum and the liquid is discharged by applying the discharging energy corresponding to a saturation domain where the amount of the liquid to be discharged out of the liquid discharging port is substantially saturated in accordance with the increase of the discharging energy.
