An inkjet recording apparatus includes a recording head having nozzle holes, a reserving portion that reserves ink to be supplied to the recording head, a positive-pressure supply unit that supplies positive gas pressure from the outside into the reserving portion to apply positive pressure on ink in the nozzle holes through ink reserved in the reserving portion, a first flow path through which positive-pressure gas flows from the outside into the reserving portion by the positive-pressure supply unit when the difference between the pressure of positive-pressure gas provided by the positive-pressure supply unit and the inner pressure of the reserving portion is not lower than a first predetermined value, and a second flow path through which gas flows out from the reserving portion to the outside when the difference between the inner pressure of the reserving portion and the pressure of the outside is not lower than a second predetermined value.
