Abstract:
A liquid ejection head that can suppress variation in the circulation flow rate or the pressure of the liquid among a plurality of pressure chambers and suppress a difference in temperature distribution between adjacent element substrates to suppress image unevenness includes a plurality of ejection modules including an element substrate in which a plurality of ejection orifices that eject a liquid are aligned in an array. In one ejection module of the ejection modules adjacent to each other, the liquid is supplied from one side of an ejection orifice array, and the liquid is collected from the other side of the ejection orifice array, and in the other ejection module of the ejection modules adjacent to each other, the liquid is supplied from the other side, and the liquid is collected from the one side.
