Abstract: Based on a correction value that is stored in a correction value storage, correcting circuitry corrects printing data that is acquired according to a printing instruction that is transmitted from a higher-level device. When an image forming unit determines, in response to reception of the printing instruction, that timing of reception of the printing instruction meets a given condition, the image forming unit suspends the printing instruction, requests the correcting circuitry to update the correction value, and forms an image based on the printing data that is corrected by the correcting circuitry. When the image forming unit requests the correcting circuitry to update the correction value, the correcting circuitry updates the correction value that is stored in the correction value storage based on the image that is formed by the image forming unit according to measurement pattern printing data that is stored in a measurement pattern storage.
