In a line-type printer head, a plurality of head chips are arranged side by side in a printing direction, and each of the head chips has a plurality of discharging portions aligned in the printing line direction so as to discharge ink droplets. A plurality of discharging portions of the adjoining head chips are placed in an overlapping section, and the landing interval between ink droplets discharged from the discharging portions in the overlapping section of one of the adjoining head chips and the landing interval between ink droplets discharged from the discharging portions in the overlapping section of the other head chip are different from each other.
