Abstract
An image forming apparatus includes a print device, a tone correction unit, a peripheral light quantity drop detecting unit, and a color value correction unit. The tone correction unit corrects a tone characteristic of the print device based on color values of a plurality of color patches of each of a reference chart and a test chart in an image. The image is generated by simultaneously taking a reference sheet and a test sheet by an imaging device. The reference chart is drawn on the reference sheet. The test chart is printed on the test sheet by the print device. The peripheral light quantity drop detecting unit detects the amount of the peripheral light quantity drop in each of the patches based on the positions and luminances of the plurality of reference regions in the image and the positions of the patches in the image.
