摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus and a gradation correction method capable of performing appropriate gradation correction when image unevenness or reflection unevenness occurs in the traveling direction of an image carrier.SOLUTION: An image forming part 40 transfers a plurality of gradation patches having respective densities different from each other along the traveling direction of an intermediate transfer belt 421 to a first detection target area 500 and transfers a reference patch which is a black solid image having the maximum density to a second detection target area 510 positioned at the same position as the first detection target area 500 in the traveling direction. A density detection sensor 43 detects the reflection densities of the gradation patches and the reflection density of the reference patch. A gradation correction part (a control part 10 and an image processing part 30) corrects, based on the reflection density of the reference patch, the output gradation values of the gradation patches calculated from the reflection density of the gradation patches and obtains the gradation characteristics of the image forming part 40 from the corrected output gradation values and the input gradation values of the gradation patches to creates the gradation correction data based on the gradation characteristics.
