Claim Text:
1. An image forming device comprising: (A) a first nozzle group in which nozzles that eject a first photo-curable ink are aligned in a predetermined direction; (B) a second nozzle group in which nozzles that eject a second photo-curable ink are aligned in the predetermined direction, and are arranged distanced from the first nozzle group on one side in the predetermined direction; (C) a light irradiation unit which cures the photo-curable ink by radiating light on the photo-curable ink ejected onto a medium, and is arranged by being extended at least in the predetermined direction, by being stretched at least from an end portion on one side of the first nozzle group in the predetermined direction to an end portion of the other side of the second nozzle group in the predetermined direction; and (D) a control unit which causes an ejection operation and a transport operation to be repeatedly executed; and (E) a third nozzle group in which ink is not ejected is provided between the first nozzle group and the second nozzle group in the predetermined direction, wherein in the ejection operation, the photo-curable ink is ejected from the nozzle while moving the nozzle groups and the light irradiation unit in a movement direction which intersects the predetermined direction, wherein in the transport operation, a medium is relatively moved in the predetermined direction relative to the nozzle groups and the light irradiation unit, the control unit forming a main image which is formed using the first photo-curable ink, and a background image which is overlappingly formed using the second photo-curable ink.
