A UVLED ( 62 ) or a UVLED array unit ( 64 ) is employed in the UV-ray emitting body of a UV-ray irradiating means ( 60 ) for curing a UV-ink drop, shot at the surface of print media ( 50 ) mounted on a platen ( 20 ) from the ink jet head ( 30 ) of an ink jet, by irradiating it with UV-rays. Power consumption of the UV-ray irradiating means ( 60 ) is suppressed greatly, the UV-ray irradiating means ( 60 ) is reduced in size and weight or simplified, waiting time of the UV-ray irradiating means ( 60 ) is eliminated when the UV-ray emitting body is lighting, or generation of ozone is prevented when the UV-ray emitting body is lighting.
