摘要:
Plural nozzle arrays of which each comprises plural nozzle holes 247a from which ink is ejected are arranged slantingly in a main scanning direction. A distance between a first arbitrary nozzle hole 247a-1 and a second nozzle hole 247a-2, in a nozzle array adjacent to the array to which this first nozzle hole 247a-1 belongs, which is adjacent to the first nozzle hole 247a-1, and a distance between the first nozzle hole 247a-1 and a third nozzle hole 247a-3, in the nozzle array to which the second nozzle hole 247a-2 belongs, which is further adjacent to the first nozzle hole 247a-1 are different from each other.
