摘要： An image forming apparatus has an endless belt which serves as an image carrier is characterized by reduced image misregistration and reduced machining cost. When the endless belt feed path is divided into a path from a drive roller to a tension roller, and a path from the tension roller to the drive roller, the eccentricity of an idle roller located on the path on the side including a latent image forming point is set to a value smaller than that of an idle roller located on the path not including the image forming point.

摘要： According to one embodiment, an image forming apparatus includes an image carrier, a image forming unit, a measurement unit and a controller. The image carrier includes a central region on which a target image as an object of an image forming is formed and a peripheral region placed outward of the central region. The image forming unit forms a reference image on the peripheral region and the central region, before the image forming is started. Also, the image forming unit forms the target image on the central region based on a preset condition and a third reference image on the peripheral region, during the image forming. The measurement unit measures a physical quantity for the reference images.
