Abstract: A fixing device configured to fix a toner image on a recording material by heating while conveying the recording material that bears the toner image by a nip portion, the fixing device includes a fixing roller having a rubber layer, a rotating member configured to form a contact portion between the rotating member and the fixing roller, and a pressure member configured to form the nip portion cooperatively with the fixing roller. In the fixing device, heat of the rotating member transfers to the fixing roller from the rotating member via the contact portion, and the contact portion includes a region where the pressure is increased after being decreased on a downstream side further than a center of the contact portion in the rotational direction of the rotating member.

Abstract: A fixing apparatus includes a roller, a first unit configured to heat the roller, the first unit including a first tubular film, a heating portion forming member to form a heating portion with the roller, and a first guide member dotted with first protruding portions contacting the inner surface of the first tubular film, and a second unit configured to form a nip portion with the roller, the second unit including a second tubular film, a nip portion forming member to form the nip portion with the roller, and a second guide member dotted with second protruding portions contacting the inner surface of the second tubular film, wherein there is a non-overlapping area between the first protruding portions and the second protruding portions in a generatrix direction of the roller.
