Abstract:
1. An inkjet recording device comprising: a first pair of rollers and a second pair of rollers that is disposed on a downstream side of said first pair of rollers in a conveyance direction, said first and second pairs of rollers being configured to convey a sheet in the conveyance direction that is along a conveyance path while nipping the sheet, such that a leading end of the conveyed sheet is positioned on a front side of a trailing end of the conveyed sheet in the conveyance direction; a recording head disposed between said first pair of rollers and said second pair of rollers in the conveyance direction, said recording head being configured to eject ink droplets toward the conveyance path through nozzles that are arranged in the conveyance direction; and a controller configured to cause said first and second pairs of rollers to perform an intermittent conveyance for alternately conveying and stopping the sheet, and to cause said recording head to perform an image recording on the sheet by ejecting the ink droplets onto the sheet when the sheet is stopped in the intermittent conveyance, wherein said controller is configured to cause said recording head to perform the image recording in accordance with a first image-recording data, before the trailing end of the sheet passes through said first pair of rollers, wherein said controller is configured to cause said recording head to perform the image recording in accordance with a second image-recording data which is based on said first image-recording data and which has a higher image resolution than said first image-recording data, after the trailing end of the sheet passes through said first pair of rollers, wherein said nozzles are arranged in a row which extends in the conveyance direction and which has a given length as measured in the conveyance direction, and wherein said controller is configured to set a conveyance distance as an amount of each one of intermittent conveyance motions of the intermittent conveyance, such that the conveyance distance is smaller than the given length of said row of said nozzles.
