Abstract
The present disclosure provides a consumable, a consumable chip, and a communication method between the image forming apparatus and the consumable chip. The consumable chip is capable of being installed on a consumable, and the consumable is capable of being detachably installed on an image forming apparatus. The consumable chip includes a storage unit and a chip control unit. The storage unit is configured to store identity authentication information of the consumable. The chip control unit is configured to receive an authentication request sent by the image forming apparatus and obtain second time information, generate a second code by performing a calculation using a preset algorithm according to the obtained second time information and the pre-stored identity authentication information of the consumable, and send the second code to the image forming apparatus. The second code is configured to determine whether the consumable meets expectation.
