ABSTRACT:
A copying machine equipped with a PC counter for counting cumulative rotation time of a photoconductive drum, a development counter for counting cumulative drive time of a developing unit, a sensor for detecting deposition amount of toner onto the photoconductive drum, a sensor for detecting toner concentration in the developer, and a humidity sensor. Based on output values from the counters and sensors, a control section of the copying machine estimates the degree of consumption of a consumable article by using fuzzy inference method or neural network, and thereby decides whether the consumable article have reached an end of life.
