摘要： A fixing device (20) includes a support member (25) disposed to support a nip formation member on an inner peripheral surface of a fixing belt (21). The support member includes a parallel portion (25a) that supports the nip formation member (24) and extends parallel to a sheet transport direction in a nip portion, and a rise portion (25b) that extends from the parallel portion in a direction drawn apart from the nip portion. The rise portion is inclined to the parallel portion such that an inclination direction of the rise portion is substantially parallel to a virtual straight line (L) connecting a center of rotation (X) of the fixing belt and an inlet point (Y) of the nip portion or falls within a range of rotational angles of ± 15° by which the virtual straight line is rotated around the center of rotation of the fixing belt.

摘要： An image forming apparatus (1) includes a fixing device (20; 20S) including a fixing rotary body (21) and a heater (23) for heating the fixing rotary body (21). An opposed body (22) contacts the fixing rotary body (21) with releasable pressure therebetween to form a fixing nip (N) therebetween through which a recording medium is conveyed. A heat shield (27; 27S) is interposed between the heater (23) and the fixing rotary body (21) and movable in a circumferential direction of the fixing rotary body (21) to shield the fixing rotary body (21) from the heater (23) in a variable circumferential direct heating span (±) of the fixing rotary body (21) where the heater (23) is disposed opposite the fixing rotary body (21) directly. A controller (90) halts the heat shield (27; 27S) instantly when a fault occurs during a print job.

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.
