Abstract
In an image forming apparatus, a correction processing unit prints a test pattern using a recording head, determines ink ejection malfunction positions on the basis of a scanned image of the test pattern, sets one of first and second correction modes for each of the ink ejection malfunction positions in accordance with a density of the ink ejection malfunction position on the basis of the scanned image, and performs the correction process for the ink ejection malfunction position in the set first or second correction mode. In the first correction mode, the correction process is performed for both a nozzle corresponding to the ink ejection malfunction position and an adjacent nozzle of the nozzle. In the second correction mode, the correction process is not performed for the nozzle corresponding to the ink ejection malfunction position but is performed for the adjacent nozzle.
