PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing toner-scattering, irrespective of a toner deposition amount or a toner charge amount. SOLUTION: The image forming apparatus includes: one or a plurality of image carriers 3, an electrostatic latent image is formed on each surface thereof; an intermediate transfer belt 7 to which a toner image formed on the image carrier is primarily transferred; a secondary transfer roller 8 to which a voltage whose polarity is opposite to that of the toner is applied so as to secondarily transfer the primarily transferred toner image to a transfer material; a backup roll 13 disposed in a position facing the secondary transfer roller 8 through the intermediate transfer belt 7 so as to come in contact with the rear surface opposite to the intermediate transfer belt 7 surface on which the toner image is formed; and a conductive roller 16 disposed near the upstream side of the backup roll 13 so as to come in contact with the rear surface of the intermediate transfer belt 7. A voltage whose polarity is opposite to the charge polarity of the toner is applied on the conductive roller 16. COPYRIGHT: (C)2008,JPO&INPIT
