Abrégé
(EN) A fixing apparatus capable of improving the degree of freedom of designing a mechanism for driving a fixing belt, which is provided with a fixing roller (22), a pressure roller (24) urged against the fixing roller (22) so that the pressure roller rolls in contact therewith, a heat source-containing heating roller (28) provided on the upstream side of the fixing roller (22) with respect to the direction in which a sheet (S) supporting an unfixed toner on an upper surface thereof is transferred, a fixing belt (32) endlessly passed around the fixing roller (22) and heating roller (28) and adapted to preheat the unfixed toner on the portion of the sheet (S) which is about to pass through the contact-rolling portions of the fixing roller (22) and pressure roller (24), by receiving heat from the heat source (26), and a mechanism (44) for driving the pressure roller (24).
(FR) L'invention porte sur un appareil de fixation améliorant le degré de liberté de conception d'un mécanisme d'entraînement d'une bande fixatrice comportant: un rouleau fixateur (22), un rouleau presseur (24) appuyant sur le rouleau fixateur (22) et en contact avec lui, un rouleau chauffant (28) contenant une source de chaleur et situé en amont du rouleau fixateur (22) par rapport au sens de déplacement d'une feuille (S) dont la surface supérieure porte du tonner non fixé, une bande fixatrice (32) tournant sans fin autour du rouleau fixateur (22) et du rouleau chauffant (28), et conçue pour préchauffer le tonner non fixé se trouvant sur la partie de la feuille sur le point de franchir la zone de contact rouleau (22) fixateur/rouleau (24) presseur à l'aide de la chaleur de la source de chaleur (26), et un mécanisme (44) d'entraînement du rouleau presseur (24).
