Abstract
A fixing device includes a rotatable pressing roller, a fixing rotator to rotate in contact with the pressing roller, a nip formation pad, and a slide sheet disposed between the nip formation pad and the fixing rotator. The slide sheet includes a base material layer made of a woven fabric of spun yarn. In the base material layer, a distance between adjacent spun yarns is equal to or less than 0.4 times a width of the spun yarn in a cross-section of the slide sheet in a direction of slide movement of the fixing rotator, and, in a cross-section of the slide sheet in a longitudinal direction of the slide sheet and a direction perpendicular to the slide movement of the fixing rotator, a thickness of the spun yarn is equal to or greater than 0.2 times a width of the spun yarn.
