    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： In a fixing device (20), a pressing member (31) is pressed against a nip formation member (26) via a 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. The fixing member (21) and the pressing member (31) rotate and convey the recording medium bearing the toner image through the nip (N). The heat conduction member (22) faces an inner circumferential surface of the fixing member (21) to guide the fixing member (21) sliding over the heat conduction member (22) and to transmit heat to the fixing member (21). The heat conduction member (22) includes a plurality of convex portions (50; 51) provided on an outer circumferential surface of the heat conduction member (22) and contacting the inner circumferential surface of the fixing member (21).

    摘要： A fixing device (20) includes a tubular belt holder (27), a rotatable flexible fuser belt (21), a contact member (26), a pressure member (31), and a heater (22). The tubular belt holder (27) extends in an axial direction thereof. The fuser belt (21) is looped into a generally cylindrical configuration around the belt holder. The tubular belt holder retains the fuser belt in shape as the belt rotates in a circumferential direction. The contact member (26) extends in the axial direction. The pressure member (31) extends in the axial direction. The pressure member (31) presses against the contact member through the fuser belt to form a fixing nip. The heater (22) is disposed to heat a predetermined circumferential portion (HZ) of the fuser belt. The belt holder includes a first circumferential section (S1) and a second circumferential section (2). The first circumferential section faces the heated portion. The second circumferential section faces upstream from the heated portion in the circumferential direction.
