Abstract
In an image forming apparatus, a recording head ejects ink corresponding to an image to be printed, using arranged nozzles. A control unit determines nozzles corresponding to the image to be printed, correspondingly to a position of a print sheet, and causes the recording head to eject ink from the nozzles. A correction processing performs a correction process corresponding to each of ink ejection malfunction positions in the image. Further, the correction processing unit (a) sets the ink ejection malfunction positions as targets of the correction process in advance, and (b) excludes from the targets on the basis of a sheet size of the print sheet an ink ejection malfunction position corresponding to a nozzle that is not used for the print sheet among nozzles corresponding to the plural ink ejection malfunction positions and thereafter performs the correction process for the targets.
