An upper coupling member arranged between the side plates is provided with a side frame. The separation member includes a flat support plate, a first tilted flat plate and a second tilted flat plate. Both end regions of the second tilted flat plate form positioning protuberances, and the intermediate region forms a separation portion. The flat support plate is fixed to the side frame at a plurality of fixing portions by using screws. Ends of the positioning protuberances are brought into contact with the outer peripheral surfaces of the corresponding bearing members, and the end of the separation portion is positioned maintaining a predetermined gap with respect to the outer peripheral surface of the thermally fixing roller.
