Abstract:
An image forming apparatus comprises an expendable item having a specific function, installed replaceably with respect to a main body of the image forming apparatus, wherein there are several types of expendable items, and an engine control unit. The engine control unit judges end of lifetime of the expendable item by using one of a plurality of lifetime judgment methods. The engine control unit selects a lifetime judgment method used in the judgment, according to a type of the expendable item. It makes possible to provide an image forming apparatus capable of appropriately determining the reaching of the lifetime end of expendable items.

Claim (Index 17):
The image forming apparatus according to  claim 16 , wherein\n the hardware processor selects a parallel lifetime judgment method for concurrently detecting end of lifetime according to the first method and the second method, if the information indicative of the lifetime judgment method stored in the expendable item is a third information different from the first and the second information, the hardware processor determines that the lifetime of the expendable item has come, in the case where the parallel lifetime judgment method is selected, and end of lifetime is detected in at least one of the first method and the second method, and rewriting of the information indicative of the lifetime judgment method stored in the expendable item is only possible to rewrite from the first information to the third information and rewrite from the second information to the third information.
