Abstract
An image forming device that forms a toner image on a surface of a photoreceptor, transfers the toner image to a recording material and outputs a printed recording material, includes: an intermediate transfer body that primarily transfers the toner image on the photoreceptor and secondarily transfers the toner image to the recording material; a cleaner that removes a toner left on the surface of the photoreceptor; a patch forming unit that forms a toner patch between two adjacent toner images when multiple toner images are continuously formed on the surface of the photoreceptor; a concentration detector that detects concentration of the toner patch primarily transferred to the intermediate transfer body from the photoreceptor; and a patch adjuster that adjusts toner amount used for forming the toner patch based on a result detected by the concentration detector.
