Abstract: A fixing device including fixing belt, a heat source to heat the fixing belt, a rotating member in engagement with an outer circumferential surface of the fixing belt, a nip forming member to pressurize the fixing belt, thereby forming a fixing nip between the fixing belt and the rotating member, and sliding members on both ends of the fixing belt and rotated together with the fixing belt. A rotation center of each of the sliding members is on an upstream side compared to a rotation center of the rotating member along a feeding direction of a printing medium, and a shortest distance between a tangential line of an outer circumferential surface of each of the sliding members and the rotation center of the rotating member is equal to or greater than a shortest distance between the fixing nip and the rotation center of the rotating member.
