摘要： A liquid discharging unit includes a first color nozzle group that includes nozzle arrays each in which nozzle holes for discharging liquids of process colors are arranged in a sub scanning direction perpendicular to a main scanning direction; a second color nozzle group that is provided on upstream side in the sub scanning direction with respect to the first color nozzle group and includes nozzle arrays each in which nozzle holes for discharging liquids of process colors are arranged in the sub scanning direction; and at least one auxiliary nozzle group that is provided between the first color nozzle group and the second color nozzle group and includes nozzle arrays each in which holes for discharging liquids of colors different from the process colors are arranged in the sub scanning direction. The nozzle groups are respectively arranged to be shifted from each other in the main scanning direction.
