Abstract
An image forming apparatus is provided for performing image formation by developing an electrostatic latent image formed on an image bearing member using a recording material. The apparatus includes an input unit configured to input a color image to be formed, a specifying unit configured to specify an important color of the input color image, and a patch setting unit configured to set a patch on the basis of the important color. The apparatus also includes a calorimetric measurement unit configured to calorimetrically measure a developed patch obtained by developing an electrostatic latent image of the patch formed on the image bearing member, and a calibration unit configured to perform calibration on the basis of the calorimetric value obtained by the calorimetric measurement unit.
