ABSTRACT:
The full line type liquid droplet ejection head comprises: a plurality of pressure chambers; and a plurality of nozzles which correspond to the pressure chambers and are two-dimensionally arranged through a length corresponding to a full width of a recording medium conveyed in a sub-scanning direction relatively to the liquid droplet ejection head, wherein a nozzle pitch Pn in the sub-scanning direction between two of the nozzles mutually adjacent in the sub-scanning direction satisfies the following formula: Pn=(m+k)×Pd, where Pd is a minimum pitch between dots in the sub-scanning direction corresponding to a recording resolution in the sub-scanning direction of the dots on the recording medium, m is an integer not less than 1, and k is an arbitrary constant set in a range of 0.4≦k≦0.6.
