Abstract
The present invention is able to print high-grade images by reducing the adverse effect of misdirection of ink in the joining portion between adjacent nozzle lines. To achieve this, an ink jet print head includes a plurality of chips in each of which adjacent nozzle lines are formed. The relative positions of the chips are set depending on the amounts of misdirection of ink ejected from overlapping nozzles in the joining portion.
