An inkjet printer including a UVLED unit which emits ultraviolet light to a print medium supported on a supporting table to cure UV ink droplets deposited on the print medium. The inkjet printer further includes a controller which adjust the light quantity of ultraviolet light, emitted from the UVLED unit to the UV ink droplets deposited on the print medium, from a light quantity for temporary curing to a light quantity for final curing, and a control unit capable of selecting between a two-stage curing mode in which UV ink droplets deposited on the print medium are temporarily cured ant 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 means of the UVLED unit and the controller.
