Abstract:
1. An image forming apparatus configured to form an image on a recording medium by jetting liquid droplets of a liquid to hind on the recording medium, the apparatus comprising: a transport section including: a first head comprising a first line head and a second line head, which are fixed at different positions with respect to a vertical direction to face the first transport section, each of which extends in a third direction perpendicular to the first direction and the second direction and each of which includes a plurality of first nozzles aligned in the third direction; a second head comprising a third line head and a fourth line head, which are fixed at the same positions as the first line head and the second line head respectively with respect to the vertical direction to face the second transport section, each of which extends in the third direction, and each of which includes a plurality of second nozzles aligned in the third direction; and a control device configured to control the transport section, the first head, and the second head; wherein the first head includes a first overlap nozzle group formed of the first nozzles arranged in an area in the vertical direction which has an upper end at a position of an uppermost second nozzle of the second nozzles and a lower end at a position of a lowermost second nozzle of the second nozzles; wherein the second head includes a second overlap nozzle group formed of the second nozzles arranged in an area in the vertical direction which has an upper end at a position of an uppermost first nozzle of the first nozzles and a lower end at a position of a lowermost first nozzle of the first nozzles; and wherein the control device is configured to control the transport section, the first head, and the second head so that the liquid droplets jetted from the second overlap nozzle group are landed, on the recording medium, in an area in which the liquid droplets jetted from the first overlap nozzle group have been landed.
