Abstract

The color image forming apparatus includes a CPU configured to correct a result of detecting a toner patch by a density sensor based on a result of detecting a first white reference plate by the density sensor, and to control a density or chromaticity of a toner image based on a result of detecting the toner patch by the density sensor corrected by the CPU. The CPU is configured to further correct the result of detecting the first white reference plate by the density sensor based on a result of detecting, by the density sensor, a second white reference plate for correcting the first white reference plate. With this configuration, a correction of a sensor output is performed with high accuracy, and detection accuracy of the density or the chromaticity by the sensor is enhanced.
