Abstract

PURPOSE:To reduce the frequency of replacing a latent image carrier and that of an image forming unit by providing a display means displaying that the image forming unit has to be replaced and a display means displaying that both the image forming unit and the latent image carrier have to be replaced. CONSTITUTION:When the image forming unit reaches its service life, signals from a unit life detecting means 60 are inputted to and displayed on a 1st display 61. If a photosensitive body does not reaches its life, no output from an AND circuit 62 exists, and a 2nd display 64 does not light up. When a photosensitive body becomes dead and signals from a photosensitive body life detecting means 63 are inputted to the AND circuit 62, the displays 61 and 64 keep going off unless the signals from the unit life detecting means 60 are outputted. When the life of the image forming unit is detected with photosensitive body life detecting signals outputted, both the displays 61 and 64 light up to display that the potosensitive body and the image forming unit are to be replaced. Thus the frequency of replacing the latent image carrier and that of the image forming unit can be reduced.
