Abstract
A calibration method for calibrating a color image forming apparatus includes detecting the color of a patch formed on a recording medium by the color image forming apparatus using a color sensor, converting a detected color signal in a first color specification system into a color signal in a second color specification system, and adjusting at least one of the image forming conditions for the color image forming apparatus, based on the color signal converted in the conversion step, where the conversion conditions in the color signal conversion are different depending on the attributes of the patch.
