Abstract
According to one embodiment, an image forming system includes a photoreceptor system, first and second detection system, a controller, and a determination system. The photoreceptor system having a rotational shaft in a longitudinal direction. The first detection system detects whether there is an abnormality on a surface of the cylindrical photoreceptor system at a first position. The second detection system detects whether there is the abnormality on the surface of the cylindrical photoreceptor system at a second position. The controller causes the second detection system to start detecting of the abnormality at a point in time after a waiting time. The determination system determines damage occurred at a surface position of the surface of the cylindrical photoreceptor system if the second detection system detects the abnormality at the surface position at which the first detection system detected the abnormality.
