Abstract:
A fixing device includes a fixing member, a pressing member, a contacting member fixed in an interior of the fixing member, and a heating unit that emits infrared ray. A mechanism concentrates the infrared ray emitted by the heating unit into a nip portion between the fixing member and the pressing member and into an area narrower than a width of the nip portion.
