FIELD: physics.
SUBSTANCE: disclosed is a consumable chip, a consumable, an image forming apparatus and an image forming control method. Consumable chip is detachably mounted on the consumable and the consumable is detachably mounted on the image forming device. Consumable chip includes a chip control unit, and the chip control unit is used to obtain a response signal based on the request signal and process the response signal based on a predetermined rule to generate verification data, and the verification data are used to determine whether the consumable is a consumable that meets the preset requirement.
EFFECT: consumable chip generates verification data by processing a response signal in accordance with predetermined rules, so that verification data received by the imaging device, include both a response signal and auxiliary verification data obtained in accordance with the response signal, thereby improving reliability of verification of the image forming device on a consumable chip.
