Abstract
An image forming apparatus includes an apparatus body, a toner cartridge, a replaceable part, a controller and an apparatus body memory. An operating mode of the controller is set to one of a subscription mode and a normal mode. The controller is configured to perform processes in accordance with the set operating mode. The apparatus body memory is configured to store life information indicating a remaining life of the replaceable part attached to the apparatus body. The controller is configured to switch a control between: a control for allowing an extended use of the replaceable part; and a control for restricting the extended use of the replaceable part, according to the set operating mode. The extended use is defined as use of the replaceable part even after the replaceable part exceeds the remaining life indicated by the life information stored in the apparatus body memory.
