摘要： A fixing device to fix a toner image on a sheet includes a first rotary member that rotates in a predetermined direction and a second rotary member that contacts an outer circumferential surface of the first rotary member. A stationary member is fixed inside the first rotary member to press the first and second rotary members together to form a nip portion between the rotary members. A reinforcement member is fixedly provided inside the first rotary member and pressed against the stationary member. The fixing device includes heat source to heat the first rotary member and a reflector to reflect heater light emitted from the heat source toward the first rotary member.

摘要： A fixing device includes a hollow, open-sided stationary heat roller, a flexible fuser belt, a fuser pad, a rotatable pressure member, a reinforcing member, and a sealing mechanism. The heat roller defines an elongated longitudinal side opening that opens into a hollow interior thereof. The fuser belt is looped for rotation around the heat roller to transfer heat radially outward from the roller circumference. The fuser pad is held substantially stationary along the roller opening outward from the roller interior and inward from the loop of the fuser belt. The pressure member is pressed against the fuser pad through the fuser belt to form a fixing nip. The reinforcing member is disposed within the roller interior to thrust against the fuser pad through the roller opening. The sealing mechanism is disposed on the roller opening to prevent foreign matter from entering the roller interior through the roller opening.
