Abstract
In image forming apparatus, a control unit determines nozzles corresponding to the image to be printed, correspondingly to a position of a print sheet, and causes a recording head to eject ink from the nozzles. A correction processing unit performs a correction process corresponding to each of plural ink ejection malfunction positions in the image. If the number of the ink ejection malfunction positions detected with a predetermined ink droplet size exceeds a predetermined upperlimit value, the correction processing unit prints a test pattern using the control unit with an ink droplet size larger than the predetermined ink droplet size, determines as a preferential ink ejection malfunction position an ink ejection malfunction position that ink ejection malfunction is also detected in the test pattern on the basis of a scanned image of the test pattern, and preferentially performs the correction process for the preferential ink ejection malfunction position.
