PROBLEM TO BE SOLVED: To suppress variations in discharge performance by discharging bubbles in a liquid while continuing printing, and reducing channel resistance.SOLUTION: A liquid discharge head 100 is equipped with pressure chambers 102 which store liquid, and discharge ports 103 which communicate with the pressure chambers 102. The pressure chamber is equipped with pressurizing means for pressurizing the liquid in the pressure chamber, and has a liquid discharge substrate 101 on which a plurality of liquid discharging portions discharging the pressurized liquid from the discharge port 103 is provided, and a liquid storage chamber 124 contacting with a back surface positioned on the opposite side to the discharge port of the liquid discharge substrate 101. The liquid storage chamber 124 is divided into at least one common liquid channel 112, and a first common liquid chamber 111. The common liquid channel 112 is communicated with one of a plurality of inlets of the pressure chambers and a plurality of outlets of the pressure chambers, and the first common liquid chamber 111 is communicated with the other.SELECTED DRAWING: Figure 1 |
