Image carrier and image forming apparatus

摘要

An image carrier is provided with a support base that has the photosensitive layer, an image forming area for forming an electrostatic latent image and an information recording layer formed in an area except the image forming area on the surface for reading/writing of information by a beam. An image forming apparatus is provided with a detecting unit for optically detecting information recorded on the information recording layer and a controller for identifying the status of the image carrier from the detection result by the detecting unit.
