To bring a recording head into a liquid ejectable state by reducing waste ink.SOLUTION: A recording device according to the present invention has a recording head which has: an ejection port surface provided with an ejection port; a recording element which generates energy for ejecting liquid from the ejection port; a pressure chamber provided at a position facing the recording element; a first flow channel communicating with the pressure chamber via a first port different from the ejection port and a second flow channel communicating with the pressure chamber via a second port different from the ejection port, wherein the liquid is ejected from the ejection port through the pressure chamber. The recording device further has; acquisition means which acquires information concerning a time during which the liquid is not ejected from the ejection port; and circulation means which circulates the liquid so that the liquid flows from the first flow channel to the second flow channel through the pressure chamber. When the time indicated by information acquired by the acquisition means exceeds a prescribed time, the circulation means circulates the liquid from the first flow channel to the second flow channel through the pressure chamber.SELECTED DRAWING: Figure 12 【課題】廃インクを低減し、記録ヘッドを液体吐出可能な状態にする。【解決手段】本発明は、吐出口が設けられた吐出口面と、前記吐出口から液体を吐出するエネルギーを生成する記録素子と、記録素子と対向する位置に設けられた圧力室と、前記吐出口とは異なる第１の口を介して前記圧力室と連通する第１の流路と、前記吐出口とは異なる第２の口を介して前記圧力室と連通する第２の流路と、を有し、前記圧力室を通って前記吐出口から液体が吐出される記録ヘッドと、前記吐出口から液体を吐出していない時間に関する情報を取得する取得手段と、前記第１の流路から前記圧力室を通って前記第２の流路に液体が流れるように前記液体を循環させる循環手段と、を有し、前記取得手段が取得した情報が示す時間が所定時間を超えた場合、前記循環手段は前記第１の流路から前記圧力室を通って前記第２の流路へと前記液体を循環させる記録装置である。【選択図】図１２
