Abstract:
1. An inkjet printer to eject ultraviolet curable ink, said inkjet printer comprising: ejecting means for ejecting ultraviolet curable ink to a recording medium; ultraviolet light irradiation means for emitting ultraviolet light to the ultraviolet curable ink ejected from said ejecting means and deposited on the recording medium, said ejecting means and said ultraviolet light irradiation means being integrally formed, said ultraviolet light irradiation means being arranged only at a location that is downstream of said ejecting means as said ejecting means and said ultraviolet light irradiation means move integrally in a scanning direction and upstream of said ejecting means as said ejecting means and said ultraviolet light irradiation means move integrally in a return path direction that is opposite to the scanning direction; and light quantity changing means for changing a light quantity of the ultraviolet light emitted from said ultraviolet light irradiation means to the ultraviolet curable ink, wherein said light quantity changing means controls said ultraviolet light irradiation means to emit ultraviolet light of a first light quantity for temporarily curing the ultraviolet curable ink as said ejecting means and said ultraviolet light irradiation means move integrally in the scanning direction, and, after that, controls said ultraviolet light irradiation means to emit ultraviolet light of a second light quantity for finally curing the ultraviolet curable ink as said ejecting means and said ultraviolet light irradiation means move integrally in the return path direction.
