Claim Text:
1. An ink jet recording apparatus comprising: a head that applies liquid droplets of a photo-curable ink composition on a recording medium from a plurality of nozzle holes; a carriage in which the head is mounted, the head being moved in a first direction by an operation of the carriage so as to eject the liquid droplets by being relatively scanned with respect to the recording medium; a first light source and a second light source that are mounted on the carriage so as to move together with the head in the first direction and that illuminate the liquid droplets applied on the recording medium, the first and second light sources being provided at a same side of the head in the first direction; and a third light source that is disposed at a medium downstream side in a medium movement direction of the recording medium, wherein the photo-curable ink composition has a photo radical polymerization property and contains at least one of an acrylic ester series having an acryloyl group, the liquid droplets are illuminated by the first light source and the second light source so that the photo-curable ink composition is cured, the first light source and the second light source are spaced apart from each other so that the liquid droplets are illuminated by the second light source after the first light source stops illuminating the liquid droplets, and after the liquid droplets are illuminated by the first light source and the second light source, the liquid droplets are further illuminated by the third light source so that the photo-curable ink composition is further cured.
