Patent ID: 8025386

Claim:
An inkjet recording apparatus comprising: a recording head including a nozzle row jetting ultraviolet curable ink on a substrate; and an LED light source including a plurality of LEDs disposed in a direction of the nozzle row, wherein the plurality of LEDs are electrically series-connected, and irradiate an ultraviolet light on the ink having been jetted onto the substrate, wherein a total illuminance of each two adjacent LEDs of the LED light source on a surface of the substrate is larger than an illuminance required for curing the ink in an entire area of a section between each two adjacent LEDs, and a maximum of the total illuminance in the section between each two adjacent LEDs is set to be less than two times a minimum of the total illuminance in the section between each two adjacent LEDs, and wherein at least one of a distance between each two adjacent LEDs and an irradiation distance from the plurality of LEDs to the substrate is set so that the maximum of the total illuminance is set to be less than two times the minimum of the total illuminance.
