Claim:
An inkjet printer comprising: medium supporting means for supporting a print medium; print head means for ejecting ink droplets while moving relative to the print medium so as to print on a surface of the print medium; ultraviolet light irradiation means for emitting ultraviolet light toward the print medium supported on said medium supporting means to cure the ink droplets deposited on the print medium; irradiation light quantity control means for adjusting a light quantity of ultraviolet light emitted from said ultraviolet light irradiation means to the ink droplets deposited on the print medium in a range from a light quantity for temporarily curing the ink droplets to a light quantity for finally curing the ink droplets; and mode switching means for selecting between a two-stage curing mode in which UV ink droplets deposited to the print medium are temporarily cured and are then finally cured and a single-stage curing mode in which UV ink droplets are finally cured by an irradiation with ultraviolet light at one time by said ultraviolet light irradiation means and said irradiation light quantity control means.
