Summary: | PROBLEM TO BE SOLVED: To provide an electrophotographic image forming apparatus which can properly predict the life of a photosensitive drum. SOLUTION: This apparatus is equipped with a rotation time counter TC which measures the rotation time of the photosensitive drum 91 and a means which counts sheets of recording paper used for image formation. When the rotation time of the photosensitive drum 91 exceeds a specific time or when the number of sheets of recording paper used for the image formation exceeds a specific number, the life of the photosensitive drum 91 is predicted according to the rotation time or the number of sheets of recording paper respectively and a user is notified of the replacement period of the photosensitive drum 91. |
