ABSTRACT:
In an ink jet type recording head, nozzles 190 to 197 for jetting droplets of ink are arranged in such a manner that these nozzles are located along two line segments L1 and L2 which are inclined mutually in opposite directions with respect to a main scanning direction, and the two line segments constitute a substantially V-shape, so that problems such as a printing quality deterioration phenomenon and ink chamber interference can be solved, and higher printing qualities can be realized at high printing density.
