Method and an image forming apparatus with a magnetic recording layer

摘要

An image forming apparatus includes an image carrier that includes a tube, a photosensitive layer provided at a part of the tube for forming an image forming area, and a magnetic recording layer provided at a part of the tube that is outside of the image forming area. The image forming apparatus also includes a writing/reading device that writes a using history of the image carrier on the magnetic recording layer. An information processing method includes recording a measured time information of a photosensitive drum on a magnetic recording layer on the photosensitive drum.
