The inkjet recording apparatus has a color ink recording head to jet color
ink toward a recording medium; an invisible ink recording head to jet
invisible ink toward the recording medium; and a light irradiating device
to irradiate light toward the recording medium to cure the ink. A control
section causes the color ink to be jetted then the light irradiating
device irradiates the color ink, thereafter the invisible ink is jetted,
and finally the light irradiating device irradiates the invisible ink
after a lapse of a certain time from the invisible ink jetting.
