PROBLEM TO BE SOLVED: To achieve control of energy consumption and long lifetime of a light source when ejecting a liquid cured by ultraviolet and irradiating ultraviolet to the liquid.SOLUTION: A printer 10 includes: a recording head 120 that ejects a liquid cured by ultraviolet; and an irradiation part that irradiates ultraviolet to the liquid. The recording head 120 includes: a first discharge port to eject a first liquid that absorbs light of a first wavelength range; a second discharge port to eject a second liquid that absorbs light of a second wavelength range on a long-wavelength side than the first wavelength range; a third discharge port to eject a third liquid that absorbs light of a third wavelength range on a long-wavelength side than the second wavelength range. The irradiation part can execute irradiation in a first dose to cure a first liquid, irradiation in a second dose to cure a second liquid, and irradiation in a third dose to cure a third liquid. The first dose is larger than the second dose, and the third dose is equal to the second dose. |
