Patent ID: 8042929

Claim:
An ink jet recording apparatus for recording images in a recording medium having an ink absorbability, comprising: a plurality of recording heads arranged in a scanning direction on a carriage structured to reciprocate in the scanning direction, each of the plurality of recording heads including a nozzle for jetting a photocurable ink onto the recording medium; a first light source structured to emit light having a first emission spectrum; and at least two second light sources each structured to emit light having a second emission spectrum whose peak wavelength is shorter than a peak wavelength of the first emission spectrum; wherein the first light source is disposed between two adjacent recording heads among the plurality of recording heads in the scanning direction; a first one of the at least two second light sources is provided at a first end of the carriage in the scanning direction, and a second one of the at least two second light sources is provided at a second end of the carriage in the scanning direction, such that the plurality of recording heads are provided between the first one of the at least two light sources and the second one of the at least two second light sources in the scanning direction, so that the first light source irradiates the photocurable ink landed on the recording medium and thereafter at least one of the at least two second light sources irradiates the photocurable ink.
