Image forming apparatus having counters for counting frequency of use of parts

摘要

An image forming apparatus having a process maintenance (PM) counter which counts the frequency of use of a part from the execution of maintenance of the part, and a life counter which counts the frequency of use of a part from when the part is replaced. The counting value of both counters are displayed selectively. The image forming apparatus has a reset switch which resets the PM counter when the counting value of the PM counter is displayed, and resets both the PM counter and the life counter simultaneously when the counting value of life counter is displayed, so as not to forget to reset the PM counter when the life counter is reset.
