<p><P>PROBLEM TO BE SOLVED: To provide an image forming device which prevents the adhesion/fixation of toner onto a case and extends a replacement cycle of a development station. <P>SOLUTION: The image forming device includes an image carrier having a surface onto which an electrostatic latent image is formed, the development station including the case made of a conductive body and one or more developer rollers which supply the 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 standard concentration toner image forming unit which forms a standard concentration toner image on the surface of the image carrier, a toner adhesion amount detecting unit 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 case bias voltage control unit 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 toner adhesion amount detecting unit. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
