Abstract
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.
