PROBLEM TO BE SOLVED: To control a cleaning operation before a recording operation when changing a recording mode.SOLUTION: An ink jet recording device comprising a recording head which has a nozzle arrangement area in which plural nozzles for discharging an ink are arranged, and which performs a recording operation for recording on a recording medium, and cleaning means which contacts the recording head and performs a cleaning operation, in which a change operation by which an area which the recording medium passes is changed with respect to the nozzle arrangement area. The ink jet recording device comprises: first acquisition means which acquires information concerning an end part passage position which an end part of the recording medium passes with respect to the nozzle arrangement area in a first recording operation before performance of the change operation; second acquisition means which acquires information concerning a passage area which the recording medium passes with respect to the nozzle arrangement area in a second recording operation after performance of the change operation; and control means which controls the cleaning operation which is performed by the cleaning means before performance of the second recording operation on the basis of results of the first acquisition means and the second acquisition means.SELECTED DRAWING: Figure 10 【課題】 記録モードを切替える際に、記録動作前に行うクリーニング動作を制御する。【解決手段】 インクを吐出する複数のノズルが配列されたノズル配列領域を有し記録媒体に記録する記録動作を行う記録ヘッドと、記録ヘッドと当接してクリーニング動作を行うクリーニング手段と、を備え、ノズル配列領域に対して記録媒体が通過する領域が変わる変更動作が行われ、変更動作が行われる前の第１の記録動作において、ノズル配列領域に対して記録媒体の端部が通過する端部通過位置に関する情報を取得する第１の取得手段と、変更動作が行われた後の第２の記録動作において、ノズル配列領域に対して記録媒体が通過する通過領域に関する情報を取得する第２の取得手段と、第１の取得手段と第２の取得手段の結果に基づいて、第２の記録動作の前にクリーニング手段が行うクリーニング動作を制御する制御手段を備える。【選択図】 図１０
