Official abstract text for this publication.
A fixing device includes a fixing rotator, a heater, a pressure rotator, a nip formation pad, and a slide aid sheet. The fixing rotator is rotatable in a rotation direction. The heater heats the fixing rotator. The pressure rotator contacts an outer circumferential face of the fixing rotator. The nip formation pad is inside a loop of the fixing rotator to form a nip between the fixing rotator and the pressure rotator. The slide aid sheet is on the nip formation pad and faces the fixing rotator. The slide aid sheet includes a carbon fiber extending in a width direction orthogonal to a rotation direction of the fixing rotator.

1 . A fixing device comprising: a fixing rotator rotatable in a rotation direction; a heater to heat the fixing rotator; a pressure rotator contacting an outer circumferential face of the fixing rotator; a nip formation pad inside a loop of the fixing rotator to form a nip between the fixing rotator and the pressure rotator; and a slide aid sheet, on the nip formation pad, facing the fixing rotator, the slide aid sheet including a carbon fiber extending in a width direction orthogonal to the rotation direction of the fixing rotator. 2 . The fixing device according to claim 1 , wherein the slide aid sheet includes: a warp extending in the rotation direction of the fixing rotator; and a weft extending in the width direction of the fixing rotator, and the weft includes the carbon fiber. 3 . The fixing device according to claim 2 , wherein the warp is made of at least one of: a heat-resistant resin; or a glass fiber. 4 . The fixing device according to claim 1 , wherein the carbon fiber includes at least one of: an acrylic fiber carbon fiber; or a pitch-based carbon fiber. 5 . The fixing device according to claim 2 , wherein the carbon fiber includes a carbon nanotube. 6 . The fixing device according to claim 5 , wherein the carbon nanotube has: a single layer structure; or two or more layer structure. 7 . The fixing device according to claim 1 , wherein the slide aid sheet holds at least one of: silicone oil, silicone grease, or fluorine grease. 8 . An image forming apparatus comprising the fixing device according to claim 1 .
