An image forming device which includes a first nozzle group, a second nozzle group, and are arranged by being deviated from the first nozzle group to one side in a predetermined direction, a light irradiation unit which is extended at least in the predetermined direction, a control unit which repeats an ejection operation in which the photo-curable ink is ejected from the nozzle while moving the nozzle group and the light irradiation unit in a direction intersecting the predetermined direction, and a transport operation of the medium in a state where a non-ejection region where the ink is not ejected is provided between the first nozzle group and the second nozzle group in a predetermined direction, and overlappingly forms a main image using the first photo-curable ink, and a background image using the second photo-curable ink.

The entire disclosure of Japanese Patent Application No: 2011-104427, filed May 9, 2011, is expressly incorporated by reference herein in its entirety.
1. Technical Field
The present invention relates to an image forming device and a method of image forming.
The invention will be described with reference to the accompanying drawings, wherein like numbers reference like elements.
FIG. 1 is a block diagram which shows the entire configuration of a printer.
FIG. 2A is a schematic perspective view of the printer. FIG. 2B is a diagram which describes the periphery of a carriage.
At least the following will be clarified according to the descriptions of the specification, and accompanying drawings.
That is, there is provided an image forming device which includes, (A) a first nozzle group in which nozzles which eject first photo-curable ink are aligned in a predetermined direction, (B) a second nozzle group in which nozzles which eject a second photo-curable ink are aligned in the predetermined direction, and are arranged by being deviated 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 to the photo-curable ink, and is arranged by being extended at least in the predetermined direction, by being stretched to an end portion on one side of the second nozzle group from an end portion of the other side of the first nozzle group in the predetermined direction in the predetermined direction, (D) a control unit which causes an ejection operation in which the photo-curable ink is ejected from the nozzle while relatively moving the nozzle group and the light irradiation unit, and a medium in a movement direction which intersects the predetermined direction, and a transport operation which relatively moves the nozzle group and the light irradiation unit, and the medium in the predetermined direction to be repeatedly executed, and forms 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, in a state where a non-ejection area in which ink is not ejected is provided between the first nozzle group and the second nozzle group in the predetermined direction.
According to such an image forming device, it is possible to suppress a defective curing of an underlying image, and to overlap the upper image with the underlying image in a state of being sufficiently cured, accordingly, an image quality may be prevented from being deteriorated.
