Abstract:
A recording head includes plural nozzle groups and a second nozzle. Each of the nozzle groups includes plural nozzles that respectively form dots, which make up an image, on a recording medium by discharging droplets. The nozzles are arranged in a straight line that is inclined with respect to a main scan direction at a predetermined angle. The plural nozzle groups are arranged in a sub scan direction such that intervals in the sub scan direction between nozzles adjacent in the sub scan direction are substantially identical and positions in the sub scan direction of nozzles belonging to the respective nozzle groups are substantially aligned. The second nozzle is disposed at a substantially central portion in the main scan direction between adjacent nozzles of nozzle groups adjacent in the sub scan direction so as not to overlap with any other nozzle in the main scan direction.
