The inkjet recording apparatus initially deposits ink on a front surface of a recording medium and subsequently deposits ink on a rear surface of the recording medium in such a manner that images are formed by the ink on the front surface and the rear surface of the recording medium, wherein, when time after depositing the ink on a first region of the front surface of the recording medium until depositing the ink on a second region of the rear surface of the recording medium which corresponds to the first region is taken to be ΔT1 (sec) and viscosity of the ink to be deposited on the first region and the second region of the recording medium is taken to be η (mPa·sec), then the inkjet recording apparatus deposits the ink on the first region and the second region in such a manner that a following relationship is satisfied: ΔT1
