Abstract
A control section of an inkjet recording apparatus forms a test chart between both ends of a recording medium in a recording-medium width direction by drawing a plurality of line sets, in each of which there are arranged a predetermined number of lines each extending in a recording-medium conveyance direction and each drawn with ink ejected from a single one of the plurality of ink ejection nozzles, by sequentially shifting the plurality of line sets by one line in the recording-medium width direction, each time the recording medium proceeds a predetermined distance in the recording-medium conveyance direction. Further, the control section detects, by using the detection section, presence/absence of ink on each of the plurality of lines drawn in the test chart, and determines presence/absence of a defective pixel, and a position of the defective pixel.
