Abstract

An image forming apparatus includes a print unit, a print control unit, a reading unit, and a processing unit. The print unit forms an image on a medium at a resolution selected from several resolutions including a first resolution and a second, higher, resolution. The print control unit controls the print unit to print an image for correction including a first test pattern for printing a test pattern for gamma correction of the first resolution at a third resolution higher than the first resolution, and a second test pattern for the gamma correction of the second resolution, on the medium at the third resolution. The reading unit reads the image for correction printed on the medium. The processing unit obtains first correction information using the gamma correction for the first resolution and second correction information using the gamma correction for the second resolution, based on the image for correction.
