IMAGE FORMING DEVICE, INITIALIZATION METHOD, AND CONTROL METHOD

There is provided an image forming apparatus that can perform initialization of a consumable memory simply. An image forming apparatus (1) includes a main casing to which a consumable (4, 20) is attached, a controller (61), and a main memory (62). The consumable includes a consumable memory (22, 42) in which lifetime information (224, 225, 426 to 428) relating to a service life of the consumable is stored. The controller is configured to perform a reception process (S 102) to receive an instruction to initialize the lifetime information, an initialization process (S401 to S403) to initialize the lifetime information stored in the consumable memory in accordance with the received instruction, and a write process (S407) to write initialization information indicating that the lifetime information was initialized into the consumable memory.
