Abstract
In an image forming apparatus, a consumable accommodates printing material and is mounted in a main casing. The consumable includes a consumable memory. A controller performs a restriction process to rewrite the first status information to indicate the used product to prohibit the consumable from being used in other image forming apparatuses in a case where first status information stored in the one of the consumable memory and a main memory indicates the new product. The controller performs an updating process to update the second status information so that the second status information indicates that the consumable can be temporarily used in the another image forming apparatus in a case where the controller receives a contract cancellation instruction. The contract cancellation instruction instructs to cancel an agreement concluded for the image forming apparatus.
