PROBLEM TO BE SOLVED: To solve the problem that in a share mode inkjet head, the discharging amount of an ink becomes larger at the end sections of an image, and the density becomes higher. SOLUTION: In a head of a three division driving, (b) a 1/3 group is printed in such a manner that a dot diameter may become smaller by reducing the discharging amount of the ink for the dots on both ends, (c) a 2/3 group is printed in the same manner, and (d) a 3/3 group is printed in the same manner. As shown in (e), in the obtained image, since three each of the dots on both end sections of the image regarding a main scanning direction are smaller compared with dots at the central section, it becomes possible to reduce such a phenomenon that the discharging amount of the ink becomes larger on the end sections of the image, and the density becomes denser.
