A head member includes a plurality of first nozzles forming a first nozzle row, a plurality of second nozzles forming a second nozzle row that is paired with the first nozzle row, and an ink supplying unit that supplies a same kind of liquid to each of the nozzles. There is a slight gap between a moving track of a first nozzle by a main scanning unit and a moving track of a second nozzle paired with the first nozzle by the main scanning unit. A controlling unit is adapted to control an ink jetting unit and the main scanning unit in such a manner that an ink jetting from the first nozzle and an ink jetting from the second nozzle paired with the first nozzle are carried out in a same main scan, based on jetting data for a same jetting unit area. According to the invention, even if main scans are not repeated, liquid jetting for the same jetting unit area can be carried out from the two nozzles.
