PROBLEM TO BE SOLVED: To lessen deterioration of a granularity of recording images due to bleeding of recording dots by sequentially recording ink drops on a recording medium from ink of a higher recording density and controlling an ink discharge amount for every discharge from each recording head. SOLUTION: At the time of recording images onto a recording medium by scanning a recording head unit 3 in an arrow A direction, recording heads 2 are arranged in an arrangement from a lower ink dye concentration to a higher ink dye concentration from the upstream to downstream of a scanning direction. Recording ink drops are recorded on the recording medium first from a recording ink of a high ink dye concentration. At this time, a set temperature of the recording head for light ink is set lower than a set temperature of the recording head for dark ink, whereby an ink discharge amount per dot from the recording head for light ink is made smaller than an ink discharge amount per dot from the recording head for dark ink. |
