摘要： An ink jet printer has a recording head, having a nozzle, for jetting ink to be cured by irradiating with an ultraviolet ray from the nozzle, and an ultraviolet ray irradiating device for irradiating the ink jetted by the recording head with a plurality of ultraviolet rays. The ultraviolet ray irradiating device has a plurality of ultraviolet ray sources respectively emitting a plurality of ultraviolet rays of a plurality of light emitting wavelength peaks different from one another. After the ink jetted from the nozzle arrives at a recording medium, an image is formed by irradiating the ink of the recording medium with the ultraviolet rays of the ultraviolet ray irradiating device and curing the ink.
