A small-sized ink jet printer capable of printing on various types of recording mediums at a lower cost, is provided. This is an ink jet printer that carries out printing by depositing UV ink which is curable by irradiation of an ultraviolet ray, on a recording medium, and irradiating ultraviolet rays on the recording medium. The printer has an UV irradiating unit to enable irradiation of an ultraviolet ray on the UV ink deposited on the recording medium. The UV irradiating unit has either a semiconductor laser or an LED, which enables emitting light the peak wavelength of which includes any one of wavelengths in an ultraviolet range which allow to cure the UV ink.
