To provide an inkjet recording device and a control method of an inkjet recording device which can reduce time required until the device is brought into a stable operation state immediately after the device is started to operate, by reducing variation in ink viscosity during stoppage of operation.SOLUTION: During stoppage of operation S101, volatilization volumes of solvents included in ink in an ink container are calculated S104 using elapsed time S102 after the solvent is supplied at the last minute and an environmental temperature S103, and control by which solvents are supplied to the ink container on the basis of the calculated volatile volumes of the solvents is performed S108. This control can keep viscosity of the ink during the stoppage of operation at a predetermined value.SELECTED DRAWING: Figure 4 【課題】稼働停止中のインク粘度の変動を少なくし、稼動開始直後に安定した稼動状態になるまでの時間を短縮させるインクジェット記録装置およびインクジェット記録装置の制御方法を提供する。【解決手段】稼動停止中においてＳ１０１、直前に溶剤を補給してからの経過時間Ｓ１０２と周囲温度Ｓ１０３を用いてインク容器内のインクに含まれる溶剤揮発量を計算しＳ１０４、計算された溶剤揮発量に基づいて溶剤をインク容器に補給する制御を行うＳ１０８。この制御により、稼動停止中のインク粘度を所定値に維持することができる。【選択図】図４
