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.

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： In an image forming apparatus, attachment/detachment guide pins (10 and 11) are disposed on a side face of a belt cartridge (12). Attachment/detachment guide grooves (30, 31, and 32) which guide the attachment/detachment guide pins (10 and 11) are disposed in a frame (29) of a main unit of an image forming apparatus. A belt tension applying mechanism including a tension link (13) and a spring (15) is disposed on the side of the apparatus main unit. When the belt cartridge (12) is to be attached to the apparatus main unit, the cartridge is attached along the attachment/detachment guide grooves (30, 31, and 32), so that the rotation shaft of a tension roller (4) is easily and surely engaged with the belt tension applying mechanism (13 and 15).

摘要： An image production apparatus includes at least one image production unit having a latent image forming device for forming a latent image on an image carrying member and a developing device for attaching toner to the latent image formed by the latent image forming device. A toner image formed by the image production unit is transferred to a transfer medium to produce an image. The image production apparatus further includes a periodicity giving device for giving periodicity to movement in a main scanning direction of the image carrying member or transfer medium. According to this periodicity, the movement time from an image forming position to a transfer position, or the movement time of a transfer medium between adjacent transfer positions is set equal to an integral multiple of the period.
