Abstract
A fixing device includes a belt having a loop, a nip formation pad inside the loop, a pressure rotator, a supplier, and a holder. The pressure rotator presses the belt against the nip formation pad to form a fixing nip. The supplier is at a position above and upstream from the nip formation pad in the traveling direction to supply lubricant to an inner face of the belt. The holder holds the lubricant adhered to the inner face of the belt. The fixing nip forms a line passing through an entrance and an exit of the fixing nip. The belt forms a tangent at a contacting point with the supplier. The tangent extends to the nip formation pad adjacent to the entrance of the fixing nip in the traveling direction. The line and the tangent form an angle that is 25 degrees or more and 55 degrees or less.
