Abstract:
The present invention provides a fixing device including a flexible cylindrical rotary member and an inner-surface opposing portion that opposes an inner surface of the rotary member at an end portion of the rotary member in a generatrix direction. The inner-surface opposing portion moves upstream in a recording material conveying direction in accordance with lateral shift of the rotary member in the generatrix direction. This restricts the lateral shift of the rotary member.

Claim (Index 1):
A fixing device that fixes an image formed on a recording material to the recording material, the fixing device comprising:\n a flexible cylindrical rotary member that rotates while contacting the recording material on which the image has been formed: a roller that forms a fixing nip portion that nips and conveys the recording material together with the rotary member; an end-surface opposing portion that opposes an end surface of the rotary member in a generatrix direction of the rotary member, the end-surface opposing portion being movable in the generatrix direction of the rotary member; an inner-surface opposing portion that opposes an inner surface of the rotary member at an end portion of the rotary member in the generatrix direction of the rotary member, the inner-surface opposing portion being movable in an upstream in a recording material conveying direction; and a holding member that movably holds the inner-surface opposing portion, the holding member including a guide that guides the inner-surface opposing portion so as to move upstream in the recording material conveying direction, wherein, when the rotary member is laterally shifted and pushes the end-surface opposing portion, the inner-surface opposing portion moves upstream in the recording material conveying direction at the fixing nip portion by a force for pushing the end-surface opposing portion by the rotary member, and pushes the inner surface of the rotary member toward the upstream in the recording material conveying direction.
