摘要:
A liquid discharge head includes a recording element board having a first face on which multiple recording elements are provided, and discharge orifices for the recording elements, where pressure chambers are formed for each recording element and liquid is discharged from discharge orifices. A liquid supply channel and a liquid recovery channel are provided in common to the plurality of recording elements, in a second face opposite to the recording element board from the first face. The pressure chambers are each made to communicate with the liquid supply channel and the liquid recovery channel by the supply ports and recovery ports respectively, and a flow from the liquid supply channel through the pressure chambers to the liquid recovery channel is generated. A composited flow resistance of the liquid recovery channel and recovery ports is greater than a composited flow resistance of the liquid supply channel and supply ports.
