Fixing device for reducing belt damage

A fixing device comprising:

• a belt having a tubular shape and extending in a longitudinal direction, the belt having a longitudinal end forming an edge of the belt;
• a drive roller to rotate the belt, to convey a print medium between the drive roller and the belt;
• a bushing located at the longitudinal end of the belt, the bushing including a shoulder adjacent to the longitudinal end of the belt and a stem extending from the shoulder to an inside of the belt to support the belt;
• and
• a guide wall adjacent to the bushing to guide the bushing to move along an arcuate path in a direction opposite to a conveyance direction of the print medium, when the belt moves toward the bushing.

A fixing device comprising:

• a belt having a tubular shape and extending in a longitudinal direction, the belt having a longitudinal end forming an edge of the belt;
• a drive roller to rotate the belt, to convey a print medium between the drive roller and the belt;
• and
• a bushing located at the longitudinal end of the belt, the bushing including a shoulder separated from the longitudinal end of the belt and a stem extending from the shoulder to an inside of the belt to support the belt, wherein the belt is displaceable in the longitudinal direction away from the shoulder of the bushing so as to prevent contact between the edge of the belt and the shoulder.

A fixing device comprising:

• a belt having a tubular shape and extending in a longitudinal direction, the belt having a first end in the longitudinal direction and a second end in the longitudinal direction, opposite to the first end;
• a drive roller to rotate the belt, to convey a print medium between the drive roller and the belt;
• and
• a support device extending inside of the belt from the first end to the second end in the longitudinal direction,
• wherein the support device has a first end in the longitudinal direction, which is adjacent to the first end of the belt, and a second end in the longitudinal direction, which is adjacent to the second end of the belt,
• wherein the first end of the support device extends outwardly from the belt toward a rearward direction that is opposite to a conveyance direction of the print medium, and
• wherein the second end of the support device extends outwardly from the belt toward the rearward direction.
