Abstract
A fixing device for fixing an image on a recording medium includes an endless fixing rotary member which is formed into a loop and comes into contact with the image on the recording medium, an opposed rotary member which is in contact with the fixing rotary member, a nip forming member provided inside the loop of the fixing rotary member to be in contact with the opposed rotary member via the fixing rotary member to form a nip portion to which the recording medium is fed in a feeding direction, a support member which supports the nip forming member, and a heating source which heats the fixing rotary member. The nip forming member includes a downstream portion extending downstream in the feeding direction from a center of the nip portion and an upstream portion extending upstream in the feeding direction from the center and longer than the downstream portion.
