Document Type and Number:
WIPO Patent Application WO/2015/087796
Kind Code:
A1
Abstract:
The present invention eliminates deterioration of image qualities due to separated disposition and adjacent disposition of nozzle holes for forming dots adjacent to each other.
The present invention is provided with a plurality of nozzle holes (n) that are two-dimensionally disposed in a first direction parallel to a main scanning direction (X), and a sub-scanning direction (Y) in a nozzle forming surface. Two nozzle holes for forming dots (D, D) adjacent to each other in the main scanning direction are dispersively disposed such that the nozzle holes are not adjacent to each other in the sub-scanning direction, and the two nozzle holes for forming the dots adjacent to each other in the main scanning direction are disposed such that the nozzle holes are not separated to one end section and the other end section in the sub-scanning direction of the two-dimensionally disposed nozzle holes.
