Abstract

PURPOSE:To eliminate an erroneous reset operation in the course of use by integrating the cycles of copying cumulatively so as to indicate the total as the fatigue of a photosensitive body, and knowing the fatigue of the photosensitive body in order to reset the digital quantity with the change of the photosensitive body.
