To combine improvement in printing density with productivity (printing speed).SOLUTION: The ink ejection device comprises a line head, a movement part and a control part. The movement part moves the line head in a conveyance direction (a Y-axis direction) of a recording medium, the conveyance direction being a direction settled when a printing surface of the recording medium printing is defined as a front surface. The control part causes the movement part to fix a position of the line head and causes the line head to eject ink during conveyance of the recording medium. The control part causes the movement part to move the line head in the Y-axis direction during stoppage of the recording medium, and causes the line head to eject ink during movement thereof in the Y-axis direction.SELECTED DRAWING: Figure 26 【課題】印刷濃度の向上と生産性（印刷速度）を両立する。【解決手段】インク吐出装置は、ラインヘッド、移動部、制御部を備える。移動部は、記録媒体の印刷面を正面としたときの記録媒体の搬送方向（Ｙ軸方向）でラインヘッドを移動させる。制御部は、記録媒体の搬送中、ラインヘッドの位置を移動部に固定させてラインヘッドにインクを吐出させる。制御部は、記録媒体の停止中、Ｙ軸方向でラインヘッドを移動部に移動させ、Ｙ軸方向での移動中にラインヘッドにインクを吐出させる。【選択図】図２６
