Claim Text:
1. An image forming device in which a plurality of nozzles aligned in a designated alignment direction and an object to be recorded are moved relative to each other in a scan direction different from the alignment direction, wherein a plurality of pixels constituting a formed image includes dot omission pixels continuous in the scan direction by a defective nozzle included in the plurality of nozzles, adjacent pixels that are adjacent to the dot omission pixels in the alignment direction, and secondary adjacent pixels that are adjacent to the adjacent pixels at positions on a side opposite to the dot omission pixels from the adjacent pixels, the image forming device comprising: a pattern determining unit, in response to determining that dots are formed continuously in the scan direction on the dot omission pixels within a designated range in the scan direction based on recording data before supplementation of dots by the defective nozzle, and in response to determining that dots are formed continuously in the scan direction on the adjacent pixels within the designated range based on the recording data, configured to determine a dot pattern after supplementation for the plurality of pixels based on the recording data such that the dot pattern after supplementation is indicative of at least one of enlarging at least a portion of dots formed on the adjacent pixels within the designated range, and arranging dots in the secondary adjacent pixels within the designated range regardless of dot arrangement of the secondary adjacent pixels according to the recording data before supplementation of dots; and a pattern forming unit configured to form the dot pattern after supplementation.
