Patent attributes
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.
