Abstract

PURPOSE: To carry out the fatigue correction in conformity with an actual fatigue of photosensitive body by detecting-and-counting an exposure amount or exposure time of the copy size and its time in addition to the number of copy sheet in order to judge the extent of fatigue of the photosensitive body in accordance with the whole counted value.
