PROBLEM TO BE SOLVED: To provide a printer which increase an irradiation does of ultraviolet rays and thereby fully cures an ultraviolet-curable droplet. SOLUTION: In an ultraviolet irradiation unit 8, a light emitting diode 121 is arranged on an light emitting diode arrangement surface 101a arranged at a slant to an irradiation object, a reflective material 131 is arranged on a surface opposite the light emitting diode arrangement surface 101a, a pair of reflective materials 132 and 133 are arranged in positions adjacent to the sides of the light emitting diode arrangement surface 101a and the reflective material 131, and emitting light of the light emitting diodes 121 is reflected directly or by the reflective materials 131 to 133 and irradiated toward a printing medium. Since actually mounted light emitting diodes 121 are increased in number, the light amount is increased, and a droplet injected to the printing medium 1 is fully cured. COPYRIGHT: (C)2009,JPO&INPIT
