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 8):
The image forming apparatus according to  claim 6 , wherein\n the hardware processor starts detecting the end of lifetime by the second method regardless of the detection result by the first method, in the case where the extended lifetime judgment method is selected, and the value indicating the number of times of operation or the operation time of the expendable item becomes unusable, during the detection of the end of lifetime by the first method, and the hardware processor judges that the life of the expendable item has been reached, when end of lifetime is detected by the second method in a case where detection of end of lifetime by said second method was started, irrespective of detection result by said first method.
