An image forming device includes an image carrier having a surface onto which an electrostatic latent image is formed, a development station including a case made of a conductive body and one or more developer rollers, which supply toner housed in the case to the surface of the image carrier, and develop the electrostatic latent image formed on the surface of the image carrier as a toner image, a unit, which forms a standard concentration toner image of on the surface of the image carrier, a detector, which detects a toner adhesion amount of the standard concentration toner image formed on the surface of the image carrier by the standard concentration toner image-forming unit, and a voltage controller, which controls a bias voltage to be applied to the case according to a detected result of the toner adhesion amount of the standard concentration toner image by the detector.
