Zusammenfassung:	To realize longer stable ejection by enabling removal of scorch on a liquid ejection head substrate while achieving stable ejection by circulation.SOLUTION: An ink jet recorder comprises: a liquid ejection head that ejects ink from an ejection port by heat generation of a heating element; a tank storing ink supplied to the liquid ejection head; ink circulation means that controls circulation of ink between the liquid ejection head and the tank; and scorch removal means that controls a removal operation for scorch caused around the heating element. The ink circulation means controls the circulation of the ink according to the timing of the removal operation performed by the scorch removal means.SELECTED DRAWING: Figure 15 【課題】循環による安定した吐出を実現しながら、液体吐出ヘッド用基板におけるコゲの除去を可能にし、より長期的な安定した吐出を実現する。【解決手段】インクジェット記録装置であって、発熱素子が発熱することで吐出口からインクを吐出させる液体吐出ヘッドと、前記液体吐出ヘッドへ供給されるインクを貯留するタンクと、前記液体吐出ヘッドと前記タンクとの間におけるインクの循環を制御するインク循環手段と、前記発熱素子の周辺に発生するコゲに対する除去動作を制御するコゲ除去手段を備え、前記インク循環手段は、前記コゲ除去手段による前記除去動作のタイミングに応じて、インクの循環を制御する。【選択図】図１５
