Abstract
A fixing device includes an endless fixing film that can revolve, a contact member that comes into contact with an inner peripheral surface of the fixing film, a pressure roller that press-contacts the fixing film from an outside of the fixing film toward the contact member to form a fixing nip area between the fixing film and the pressure roller, a heater that heats the fixing film, and a reflective member that reflects light emitted from the heater toward the fixing film. A protective member that allows irradiation of the light to the fixing film is provided between the heater and the fixing film.
