Abstract
An image forming apparatus includes, for example, a pattern generating unit, image processing unit, image recording unit, and correction unit. The pattern generating unit generates a test pattern signal used to form a test pattern including a plurality of tone patches differing in tonality from each other. The image processing unit performs image processing on the test pattern signal according to a predetermined image processing mode out of a plurality of image processing modes related to tone characteristics. The image recording unit records the test pattern on a recording medium according to the test pattern signal processed by the image processing unit. The correction unit corrects the image processing mode based on a result of reading the test pattern recorded on the recording medium. In particular, the image recording unit records a background pattern around periphery of the test pattern.
