摘要： A fixing device includes a fixing belt that is endless and rotatable in a rotation direction and a nip former stretching the fixing belt. A pressure rotator presses against the nip former via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator, through which a recording medium is conveyed. A presser is disposed downstream from an exit of the fixing nip in the rotation direction of the fixing belt. The presser brings the fixing belt into contact with the pressure rotator. A mover is coupled to the presser to move the presser between a contact position where the presser brings the fixing belt into contact with the pressure rotator and an isolation position where the presser isolates the fixing belt from the pressure rotator.

摘要： A fixing device includes a fixing belt that is rotatable and a pressure rotator that is pressed against the fixing belt to form a fixing nip therebetween. A polishing roller separably contacts the fixing belt and slides over an outer circumferential surface of the fixing belt while the polishing roller is pressed against the fixing belt. At least one support supports and stretches the fixing belt. A polishing aid, which is disposed opposite the polishing roller via the fixing belt, supports and stretches the fixing belt. The polishing roller is disposed opposite the polishing aid via the fixing belt to form a polishing nip between the polishing roller and the fixing belt while the polishing roller is pressed against the fixing belt. The polishing roller changes a rotation locus of the fixing belt along at least a part of a circumferential face of the polishing roller.

摘要： A fixing device includes a flexible fuser belt, a stationary, tubular belt holder, a heater, a stationary fuser pad, and a rotatable pressure member. The flexible fuser belt is looped into a generally cylindrical configuration for rotation in a circumferential, rotational direction thereof. The tubular belt holder is inside the loop of the fuser belt to retain the belt in shape during rotation. The heater is inside the belt holder to emit infrared radiation for heating the belt. The fuser pad is inside the loop of the fuser belt. The pressure member is opposite the fuser pad with the fuser belt interposed between the fuser pad and the pressure member. The pressure member presses against the fuser pad through the fuser belt to form a fixing nip therebetween. The belt holder has an infrared-transmissive portion at least where the belt holder faces the heater.

摘要： A belt-roll fuser system includes a belt-roll fuser apparatus wherein a belt is entrained about at least a first internal pressure roll and a second internal pressure roll. The first internal pressure roll and the second internal pressure roll are configured to force a belt against an external pressure roll at a fusing nip, the belt conforming to the external pressure roll across substantially a length of the fusing nip. A passive belt support may interpose internal pressure rolls for ensuring a consistent fusing pressure across the length of the nip. A pressure belt may interpose the fuser belt and the internal pressure rolls.
