Abstract:
A liquid ejection head including recording element substrates each including ejection opening rows in which ejection openings ejecting liquid are arranged, the plurality of ejection opening rows being juxtaposed in a relative movement direction with respect to the printed medium. In the relative movement direction of the printed medium when the printed medium is viewed from the liquid ejection head, and in the plurality of ejection opening rows provided in the recording element substrate, among the plurality of recording element substrates, positioned on an upstream side in the relative movement direction, arrangement intervals of ejection openings in an end area of an ejection opening row positioned on a most upstream side in the relative movement direction are smaller than arrangement intervals of ejection openings in an end area of an ejection opening row positioned on a most downstream side in the relative movement direction.
