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.
Claims1
