    摘要： A fixing device includes a tubular belt holder, a rotatable, flexible fuser belt, a heater, a fuser pad, a pressure member, and a reinforcing member. The fuser belt is looped for rotation around the belt holder. The heater is disposed adjacent to the belt holder to heat the belt holder. The fuser pad is accommodated in the belt holder inside the loop of the fuser belt, and extends in an axial direction of the belt holder. The pressure member is disposed opposite the belt holder with the fuser belt interposed between the fuser pad and the pressure member. The reinforcing member is disposed inside the loop of the fuser belt to reinforce the fuser pad under pressure from the pressure member. The fuser pad includes an elongated base, multiple longitudinally spaced protrusions, a perforated, anti-friction cover, and a fastener.

    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.
