Abstract
A technique capable of preventing deterioration of image quality resulting from a band-shaped toner image created on a photosensitive surface in order to prevent so-called carrier attraction is provided. An image forming device in which, on a photosensitive surface of a photoreceptor, a first region electrified by a charger is set to be positioned at an inner side of a second region to which a predetermined potential difference is applied by a developing device in order to develop an electrostatic latent image formed in the first region with two-component developer, the device including: an intermediate transfer body that is arranged to be capable of abutting and being separated from the photosensitive surface, and has an image developed by the two-component developer transferred thereon from the photosensitive surface at a predetermined transfer position; and an abutting and separation controlling unit that separates the intermediate transfer body from the photoreceptor when a region of the second region excluding the first region on the photosensitive surface passes the predetermined transfer position.
