Abstract
An image forming apparatus includes circuitry and a reading device. The circuitry is configured to generate a plurality of patterns in different colors to form the plurality of patterns on a recording medium. The reading device is configured to read the plurality of patterns and a plurality of blank areas adjacent to the plurality of patterns from the recording medium. The circuitry is configured to detect a reading error of the plurality of patterns according to read values of the plurality of patterns and the plurality of blank areas and perform color calibration on a reference color by use of the read values of the plurality of patterns.
