Abstract:
1. A liquid ejection head comprising: a nozzle row including a plurality of nozzle openings through which liquid is ejected; an ejection surface disposed such that the nozzle row forms an angle with respect to the horizontal direction; pressure chambers each communicating with one of the corresponding nozzle openings; pressure generating members that change the pressures in the pressure chambers; a manifold serving as a common liquid chamber that supplies liquid to the plurality of pressure chambers through supply ports; and a liquid introducing port through which liquid is introduced to the manifold, the liquid introducing port being provided at a position between a center of a row of the pressure chambers and a first end located on the upstream side in the direction of gravity, the center of the row being defined by a center line that passes through the center of the row in a direction that is perpendicular to the direction of gravity such that the center line divides the row of the pressure chambers into two approximately equal halves.
