Summary:To provide a technique capable of shortening time required for recovery processing.SOLUTION: The inkjet recording device, which includes recording means having a plurality of nozzles for discharging ink by heat generation of a recording element and circulation means for executing circulation of ink on a circulation path including the recording means, has detection means for detecting an ink discharge state in a nozzle on the basis of a nozzle detection temperature when the ink is discharged, and control means which discharges the ink from the nozzle by generating heat of the recording element without circulating the ink by the circulation means during recovery processing of solving discharge failures of the ink caused by concentration of the ink, and controls the detection means to detect the ink discharge state in the nozzle.SELECTED DRAWING: Figure 12 【課題】回復処理に要する時間を短縮することができる技術を提供する。【解決手段】記録素子の発熱によってインクを吐出する複数のノズルを備えた記録手段と、前記記録手段を含む循環経路においてインクの循環を実行可能な循環手段と、を備えたインクジェット記録装置であって、インクを吐出した際のノズルの検出温度に基づいて、ノズルにおけるインクの吐出状態を検出する検出手段と、インクの濃度に起因するインクの吐出不良を解消する回復処理時に、前記循環手段によりインクを循環することなく、前記記録素子を発熱させてノズルからインクを吐出し、前記検出手段によりノズルにおけるインクの吐出状態を検出するよう制御する制御手段と、を有することを特徴とする。【選択図】図12
