Leakage of an ink remaining in a gutter or the like is prevented. An inkjet recording device includes an ink tank for retaining an ink, a nozzle for discharging the ink as ink particles to print on a printing object, an ink supply unit for feeding the ink from the ink tank to the nozzle, a gutter for recovering the ink particles which are not used in printing in the ink tank among the ink particles discharged from the nozzle, an ink recovery line for returning the ink particles recovered in this gutter to the ink tank, and an ink recovery unit disposed on this ink recovery line for recovering the ink in the ink tank. The inkjet recording device has a gas-liquid separation unit for separating a gas returned along with the ink particles through the ink recovery line, a gas supply line for feeding the gas to the gutter, and an atmosphere relief line for releasing the gas from the gas-liquid separation unit to the outside.
