Liquid ejection head

A liquid ejection head configured to eject a liquid from a plurality of nozzles, comprising a plurality of head units each of which has two nozzle rows, each nozzle row being formed by a plurality of nozzles from which the liquid is ejected and which are arranged at a predetermined nozzle pitch in a nozzle arrangement direction, the two nozzle rows being arranged in an orthogonal direction which is orthogonal to the nozzle arrangement direction,

• wherein the plurality of head units include
• a first head unit,
• a second head unit disposed so as to be spaced apart from the first head unit in the orthogonal direction such that the second head unit is shifted from the first head unit in the nozzle arrangement direction by a first distance,
• a third head unit disposed between the first head unit and the second head unit in the orthogonal direction such that the third head unit is shifted from the first head unit in the nozzle arrangement direction by a second distance larger than the first distance,
• wherein the first head unit has, as the two nozzle rows, a first nozzle row formed by nozzles, as the plurality of nozzles, from which a first liquid is ejected and a second nozzle row formed by nozzles, as the plurality of nozzles, from which a second liquid that differs in color from the first liquid is ejected,
• wherein the second head unit has, as the two nozzle rows, a third nozzle row formed by nozzles, as the plurality of nozzles, from which the first liquid is ejected and a fourth nozzle row formed by nozzles, as the plurality of nozzles, from which the second liquid is ejected,
• wherein the third head unit has, as the two nozzle rows, a fifth nozzle row and a sixth nozzle row each of which is formed by nozzles, as the plurality of nozzles, from which the first liquid is ejected, and
• wherein the second nozzle row is more distant, in the orthogonal direction, from the second head unit than the first nozzle row and the fourth nozzle row is more distant, in the orthogonal direction, from the first head unit than the third nozzle row, or the first nozzle row is more distant, in the orthogonal direction, from the second head unit than the second nozzle row and the third nozzle row is more distant, in the orthogonal direction, from the first head unit than the fourth nozzle row.
