Abstract:
Based on a photosensitive drum life threshold value when each of the plurality of image formation execution modes is independently used, and a photosensitive drum life threshold value according to a usage rate of each of the image formation execution modes, the image forming apparatus having a plurality of image formation execution modes calculates a photosensitive drum life threshold value according to the usage rate. Then, the image forming apparatus compares the calculated photosensitive drum life threshold value with a remaining CT film thickness prediction value for the photosensitive drum to determine the life of the photosensitive drum.
