Abstract: In an image forming apparatus, a consumable includes a consumable memory. The consumable is attached to a main casing. The main casing has an opening through which the consumable is attachable. A cover is configured to open and close the opening. The controller is configured to perform: a reception process; a determination process; an initialization process; and a reading process. The reception process receives an instruction to initialize consumable memory information stored in the consumable memory. The determination process determines at least whether the cover is in an open state in accordance with the received instruction. When determining at least that the cover is in the open state, the controller performs the initialization process. The initialization process initializes the consumable memory information. The reading process reads the consumable memory information from the consumable memory while the cover is in a closed state.
