Abstract

Toner images of reference patterns having different resolutions are formed on an image carrier, image densities of the toner images of reference patterns are detected by a density sensor, and an output of the density sensor, when the detected densities equate among the reference patterns having different resolutions formed with the same image forming condition, is memorized as a reference value for calibrating the output the density sensor.
