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.
