Abstract: front page image
(EN)An image forming apparatus sequentially transfers toner images formed on a plurality of photosensitive drums onto an intermediate transfer member or a transfer material to form an image. The image forming apparatus includes an intermediate transfer belt provided with electrical conductivity, and a power supply for applying a voltage to a current supply member contacting the outer circumferential surface of the intermediate transfer belt to pass a current from the current supply member to the plurality of photosensitive drums via the intermediate transfer belt, thus primarily transferring the toner images from the plurality of photosensitive drums onto the intermediate transfer belt.
(FR)L'invention concerne un appareil de formation d'images qui transfère séquentiellement des images en toner formées sur une pluralité de tambours photosensibles vers un organe intermédiaire de transfert ou un matériau de transfert pour former une image. L'appareil de formation d'images comprend une bande intermédiaire de transfert présentant une conductivité électrique, ainsi qu'une alimentation électrique servant à appliquer une tension à un organe d'alimentation en courant qui est en contact avec la surface circonférentielle extérieure de la bande intermédiaire de transfert afin de transmettre un courant de l'organe d'alimentation en courant à la pluralité de tambours photosensibles via la bande intermédiaire de transfert, effectuant ainsi le transfert primaire des images en toner de la pluralité de tambours photosensibles sur la bande intermédiaire de transfert.
