Abstract
A fixing device includes a fixing rotator rotatable in a rotation direction, a heat source to heat the fixing rotator, a pressure rotator contacting the fixing rotator, a nip formation pad to form a fixing nip between the fixing rotator and the pressure rotator, a slide sheet, and an adhesive part. The slide sheet between the fixing rotator and the nip formation pad contacts an inner circumferential face of the fixing rotator. The slide sheet has a center part and both end parts in an axial direction orthogonal to the rotation direction. The adhesive part bonds the slide sheet to the nip formation pad. The adhesive part includes a first adhesive part on the center part and a second adhesive part on one of the end parts. The first adhesive part has a first area, and the second adhesive part has a second area smaller than the first area.
