Abstract:
1. An image forming apparatus that corrects a gradation of an image to be formed by detecting a gradation pattern, the image forming apparatus comprising: an image forming unit configured to transfer a correction toner image corresponding to the gradation pattern on a surface of an intermediate transfer medium and to form a correction image corresponding to the gradation pattern on a surface of a recording medium; a detection unit configured to detect the intensity of the correction toner image and the intensity of the correction image; an image processing unit configured to correct the gradation based on at least one of the detected correction toner image or the detected correction image, wherein the image processing unit is configured to, calculate a transfer characteristic based on the intensity of the correction toner image detected by the detection unit, calculate an image forming characteristic based on the intensity of the correction image detected by the detection unit, and correct the gradation based on at least one of the calculated transfer characteristic or the calculated image forming characteristic such that,
