摘要：
The present invention relates to a copying machine constructed so as to make maintenance, and the replacement period for components in particular, readily understandable. The apparatus includes a first counter which counts the number of copies reproduced and a second counter which counts the use frequencies of the component whose use frequencies are not countable by said first counter.
