Abstract
A fixing device comprising a fixing belt, a rotating member arranged to be in engagement with an outer circumferential surface of the fixing belt, a nip forming member to press the fixing belt, to form a fixing nip between the fixing belt and the rotating member, and sliding members on both ends of the fixing belt and to rotate together with the fixing belt.
Claims20
A fixing device to apply pressure to a printing medium, comprising:
- a fixing belt arranged to be rotatable;
- a rotating member arranged to be in engagement with an outer circumferential surface of the fixing belt;
- a nip forming member to press the fixing belt, to form a fixing nip between the fixing belt and the rotating member;
- and
- sliding members arranged on both ends of the fixing belt and to rotate together with the fixing belt,
- wherein a circumference of an outer surface of each of the sliding members is in partial contact with an inner surface of the fixing belt.
A fixing device to apply heat and pressure to a printing medium for an image forming apparatus, comprising:
- a fixing belt arranged to deliver heat in contact with a surface of the printing medium;
- a rotating member arranged to press-contact to an outer circumferential surface of the fixing belt, to form a fixing nip between the fixing belt and the rotating member;
- and
- a nip forming member to press an inner circumferential surface of the fixing belt,
- wherein the nip forming member includes a protrusion protruding from a lower surface of the nip forming member to be in contact with the inner circumferential surface of the fixing belt, to press the inner circumferential surface of the fixing belt toward the rotating member, and
- wherein the nip forming member further includes a step portion formed in an upwardly concave shape provided on the lower surface of the nip forming member.
A fixing device to apply pressure to a printing medium for an image forming apparatus, comprising:
- a fixing belt arranged to be rotatable;
- a rotating member arranged to be in engagement with an outer circumferential surface of the fixing belt;
- a nip forming member to press the fixing belt, to form a fixing nip between the fixing belt and the rotating member;
- and
- a baffle arranged at a downstream side of the fixing nip, the baffle having
- a first end arranged closer to the fixing belt than to the rotating member and
- a second end arranged closer to the rotating member than to the fixing belt.
