(EN) IMAGE FORMING APPARATUS
(FR) APPAREIL DE FORMATION D'IMAGES
Abrégé
(EN) An image forming apparatus comprising an image carrying member for carrying a toner image; a intermediary member for carrying the toner image transferred from said image carrying member; a first transfer member for transferring the toner image from said intermediary member onto a sheet, said first transfer member having first resistance and being contacted to said intermediary member; a second transfer member for transferring the toner image from said intermediary member onto the sheet, said second transfer member having second resistance higher than the first resistance and being contacted to said intermediary member at a position downstream of said first transfer member; and voltage applying means, connected to both of said first transfer member and said second transfer member, for applying the same voltage to said first transfer member and and to said second transfer member to transfer the toner image onto the sheet.
(FR) La présente invention concerne un appareil de formation d'images comprenant un élément de transport d'images permettant de transporter une image révélée ; un élément intermédiaire permettant de transporter l'image révélée transférée depuis ledit élément de transport d'images ; un premier élément de transfert permettant de transférer l'image révélée depuis ledit élément intermédiaire sur une feuille, ledit premier élément de transfert présentant une première résistance et étant en contact avec ledit élément intermédiaire ; un second élément de transfert permettant de transférer l'image révélée depuis ledit élément intermédiaire sur la feuille, ledit second élément de transfert présentant une seconde résistance supérieure à la première résistance et étant en contact avec ledit élément intermédiaire en une position aval dudit premier élément de transfert ; et des moyens d'application de tension, connectés auxdits premier et second éléments de transfert, permettant d'appliquer la même tension auxdits premier et second éléments de transfert afin de transférer l'image révélée sur la feuille.
