Abstract:
1. 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 comprising: a fixing roller including a rubber layer; a rotating member configured to form a contact portion with the fixing roller; and a pressure member configured to form the nip portion by contacting an outer surface of the fixing roller, wherein the rotating member transfers heat to the fixing roller via the contact portion, wherein a pressure distribution in the contact portion includes a pressure decreasing region, where pressure is increased after being decreased, at a downstream side further than a center of the contact portion in the rotational direction of the rotating member, and wherein a most downstream pressure peak at the downstream side than the pressure decreasing region in the contact portion, is lower than a highest pressure peak at an upstream side than the pressure decreasing region in the contact portion.
