Claim Text:
1. A fixing apparatus that fixes a toner image on a recording medium, the fixing apparatus comprising: a film having a tubular shape; a heater having a long narrow shape and contacting an inner surface of the film; a heat conduction member that contacts, along a longitudinal direction of the heater, a surface on an opposite side of a surface of the heater contacting the film; a support member configured to support the heater via the heat conduction member; a roller that forms a pressure contact portion with the heater via the film; and a connector arranged in any one of end portions of the heater in the longitudinal direction and configured to supply electric power to the heater, wherein the toner image formed on the recording medium is heated by heat from the film and is fixed on the recording medium, wherein the pressure contact portion is configured so that a maximum pressure position thereof is in a center portion thereof in the longitudinal direction, wherein the heat conduction member includes a restriction portion configured to restrict a movement of the heat conduction member in the longitudinal direction of the heater with respect to the support member, and wherein the restriction portion is arranged in a region, of the heat conduction member, between the maximum pressure position of the pressure contact portion and an end portion of the heat conduction member which is at the same side of the connector in the longitudinal direction, and the restriction portion is not arranged in a region, of the heat conduction member, between the maximum pressure position of the pressure contact portion and an end portion of the heat conduction member which is at an opposite side of the connector in the longitudinal direction.
