ABSTRACT:
An ink-jet head has a plurality of nozzles formed on an ink-jetting surface, a plurality of manifolds, and a plurality of individual ink channel groups each of which includes a plurality of individual ink channels communicating with nozzles and one of the manifolds. Symmetric-centers of multiple nozzles with respect to one of the individual ink-channel groups are aligned in a predetermined direction. Further, when these nozzles are shifted on the ink-jetting surface such that the symmetric-centers are coincident with one another, then central axis points of the nozzles are mutually different in location. With this, there is provided an ink-jet head which makes it possible to print an image with high image-quality at a high speed.
