Abstract
In an image recording apparatus equipped with plural printing heads each for jetting ink drops having a photo-setting property towards a recording medium, a conveyance unit for conveying the recording medium to the printing heads, and each of plural light radiation devices for radiating light to the ink drops landed on the recording medium to harden, is arranged at the downstream side of each of the plural printing heads, one having largest light energy, which is located at the most downstream position among the plural light radiation devices is determined at least to satisfy the light energy necessary for hardening of the ink drops jetted by any one of the printing heads positioned upstream thereof, and the light energy becomes smaller gradually for every light radiation device in the order from the light radiation device at the most downstream position to those at more upstream positions.
