Abstract (en)

[origin: WO9429110A1] Nozzles (190 to 197) for jetting ink droplets are so disposed along two line segments (L1 and L2) diverging in opposite directions with respect to a main scanning direction. The drop of printing quality and interference in an ink chamber can be solved if the two line segments form a V-shape. Accordingly, the present invention provides an ink jet type recording head capable of high density printing with high printing quality.
