Abstract:
A fixing device includes a cylindrical film; a pressing member, and a preventing member including a preventing surface configured to prevent movement of the film in a longitudinal direction and a film rotation guiding surface. As viewed in the longitudinal direction of the film, the preventing surface includes first and second regions positioned downstream and upstream, respectively, of a nip center line with respect to a recording material feeding direction. The first region retracts from a longitudinal film end surface relative to the second region. The second region continuously extends in the recording material feeding direction from a portion upstream of a nip center line to a portion downstream of the nip center line, and has a length, with respect to a rotational direction of the film, longer at the portion upstream of the nip center line than at the portion downstream of the nip center line.

Claim (Index 1):
A fixing device comprising:\n a cylindrical film; a pressing member configured to form a nip in cooperation with said film while contacting an outer surface of said film; and a preventing member provided at a longitudinal end portion of said film and contactable to a longitudinal end surface of said film when said film moves in a longitudinal direction of said film, wherein said preventing member includes a preventing surface configured to prevent movement of said film in the longitudinal direction of said film and a guiding surface opposing an inner surface of said film and configured to guide rotation of said film, wherein in the nip, a recording material on which an image is formed is heated while being fed, and the image is fixed on the recording material, wherein as viewed in the longitudinal direction of said film, said preventing surface includes a first region positioned downstream of a nip center line with respect to a recording material feeding direction and a second region positioned upstream of the first region with respect to the recording material feeding direction, and the first region retracts in a direction of retracting from the longitudinal end surface of said film with respect to the longitudinal direction relative to the second region, and wherein the second region continuously extends in the recording material feeding direction from a portion upstream of the nip center line to a portion downstream of the nip center line, and the second region has a length, with respect to a rotational direction of said film, longer at the portion upstream of the nip center line than at the portion downstream of the nip center line.
