摘要： In the control device, the generating portion generates control data to be used by the controlling portion to form a specific image. The generating portion generates the control data such that in a first case where the printing execution unit forms the end image, the head drive portion drives the print head to eject ink droplet only from nozzles classified into the downstream nozzle group toward the downstream end region, that in a second case where the printing execution unit forms the center image the head drive portion drives the print head to eject ink droplet from the plurality of nozzles including the upstream and downstream nozzle groups toward the center region, and that, in the first case, the first nozzle does not eject ink droplet toward the center region for forming a specific part, and such that in the second case, the second nozzle ejects ink droplet for forming the specific part.

摘要： An image forming device includes a feeding unit, a recording unit, and a controller. The feeding unit includes a first feeding member and a second feeding member disposed at a downstream of the first feeding member in a feeding direction. At least one of the first feeding member and the second feeding member feeds a recording medium in the feeding direction. The recording unit is disposed between the first feeding member and the second feeding member to eject a plurality of ink droplets onto the recording medium fed between the first feeding member and the second feeding member. A plurality of ink droplets ejected onto the recording medium forms a plurality of raster lines extending in a main-scanning direction orthogonal to the feeding direction. The controller controls the recording unit to eject a plurality of ink droplets so that a plurality of first raster lines formed within a first time span has a first resolution in the feeding direction, a plurality of second raster lines formed within a second time span has a second resolution in the feeding direction, and a plurality of third raster lines formed within a third time span including a banding timing at which a trailing edge of the recording medium gets away from the first feeding member has a third resolution higher than the first resolution in the feeding direction. The second time span follows the first time span and the third time span follows the second time span. The second resolution is higher than the first resolution and lower than the third resolution.
