    摘要： In a fixing device (20), a nip formation member (22) is provided inside a loop formed by a fixing member (21) and pressed against a pressing member (31) via the fixing member (21) to form a nip (N) between the fixing member (21) and the pressing member (31) through which a recording medium bearing a toner image passes. A first heat generator (25) faces an inner circumferential surface of the fixing member (21) at a position other than the nip (N) to heat the fixing member (21). A second heat generator (24) faces the inner circumferential surface of the fixing member (21) at a position other than the nip (N) to heat the fixing member (21), and is disposed adjacent to the first heat generator (25) along the inner circumferential surface of the fixing member (21).

    摘要： A fixing device includes a rotatable, flexible fuser belt, a heater, a fuser pad, and a pressure member. The fuser belt is looped into a generally cylindrical configuration. The heater is disposed adjacent to the fuser belt to heat the fuser belt. The fuser pad is disposed inside the loop of the fuser belt, and has an outer peripheral surface thereof formed in a generally concave configuration. The pressure member is disposed opposite the fuser pad with the fuser belt interposed between the fuser pad and the pressure member. The pressure member presses in a load direction against the outer peripheral surface of the fuser pad through the fuser belt to form a fixing nip therebetween. The fuser pad includes, along the outer peripheral surface thereof, a protruding portion and an inwardly curved portion adjoining the protruding portion to face an outer circumferential surface of the pressure member.

    摘要： A fixing device (20) includes a rotatable fixing member (21) ; a heating source (23) configured to heat the fixing member (21); an opposing member (22) configured to come into contact with an outer circumferential surface of the fixing member (21) to form a nip portion (N); and a shielding member (27) configured to block heat from the heating source (23). The shielding member (27) is configured to rotate about a position different from the center of the heating source (23) so as to be movable between a shielding position and a retraction position. The shielding position is a position where the shielding member comes close to the heating source (23) to block heat from the heating source (23) to the fixing member (21). The retraction position being a position where the shielding member (27) is retracted away from the shielding position.
