An inkjet recording device comprising: an ejection head in which an ejection port to eject ink is formed; an ink tank which is connected with the ejection head through a supply channel and a collection channel and houses the ink supplied to the ejection head through the supply channel and collected from the ejection head through the collection channel; a deaeration module which is provided on a side of the supply channel and deaerates the ink; a main tank which is connected with the ink tank through a supplement channel and in which the ink supplied to the ink tank through the supplement channel is stored; a liquid level sensor which is provided in the ink tank and detects ink in the ink tank; a supply control unit which controls supply and collection of the ink; and characterized by a drawing control unit which controls ejection of the ink and performs image formation, wherein: the supply control unit supplements the ink from the main tank to the ink tank at supplement flow rate L1 (ml/sec) when the liquid level sensor detects that an ink amount in the ink tank is equal to or less than a lower limit value, and the supply control unit interrupts supplement of the ink when the ink amount in the ink tank becomes an upper limit value; a consumption flow rate of the ink ejected from the ejection head is assumed as L2 (ml/sec), an amount of the ink in the ink tank before a start of printing is assumed as T (ml), an ink amount of a lower limit value detected by the liquid level sensor in the ink tank is assumed as To (ml), a used amount up to detection in the liquid level sensor from amount T of the ink in the ink tank before the start of printing is assumed as ΔT (=T-T 0) (ml), and, in a case of L1<L2, print time limit n (sec) is calculated by equation, n ≤ ΔT / L 2 + T 0 / L 2 − L 1 and when printing does not end within the print time limit n, the printing is interrupted within the print time limit n, and the ink is deaerated by circulating the ink between the ink tank and the ejection head. an ejection head in which an ejection port to eject ink is formed;
