PROBLEM TO BE SOLVED: To provide a recording head adjustment method and image formation apparatus which can execute excellent recording by suppressing at least one of occurrence of density unevenness and deviation of image squareness.SOLUTION: In a case of adjusting the discharge timings of a first head module and a second head module that are adjacent to each other in a recording head in which the plurality of head modules having a nozzle array with a plurality of nozzles arranged at different positions in the first direction are connected in the second direction intersecting the first direction, the discharge timings are adjusted so that a complementary region recording deviation amount being a recording deviation amount in the first direction in a complementary region of a connection portion between the first head module and the second head module becomes a value between the first non-complementary region recording deviation amount and the second non-complementary region recording deviation amount being the recording deviation amounts in the first direction in the non-complementary region of the first head module and the second head module.SELECTED DRAWING: Figure 15 【課題】濃度ムラの発生及び画像直角度のずれのうち少なくとも一方を抑制して良好な記録を実現することができる記録ヘッド調整方法及び画像形成装置を提供する。【解決手段】複数のノズルが第１方向の異なる位置に配置されたノズル配列を有するヘッドモジュールを第１方向と交差する第２方向に複数個繋ぎ合わせた記録ヘッドにおいて互いに隣接する第１ヘッドモジュールと第２ヘッドモジュールの吐出タイミングを調整する場合に、第１ヘッドモジュールと第２ヘッドモジュールの繋ぎ部分の補完領域における第１方向の記録ずれ量である補完領域記録ずれ量が、第１ヘッドモジュール及び第２ヘッドモジュールそれぞれの非補完領域での第１方向の記録ずれ量である第１非補完領域記録ずれ量と第２非補完領域記録ずれ量の間の値となる吐出タイミングに調整する。【選択図】図１５
