A fixing device includes a belt having a tubular shape and extending in a longitudinal direction, and having a longitudinal end, 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, and a guide wall adjacent to the bushing. The belt is displaceable in the longitudinal direction relative to the bushing. The bushing includes 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. The guide guides the bushing to move in a direction opposite to a conveyance direction of the print medium when the belt moves toward the bushing. The stem of the bushing includes a convex portion that is in contact with an inner surface of the belt when the belt is displaced in the longitudinal direction.

Fixing device for reducing belt damage

An endless belt includes a loop-shaped support and a surface layer formed on the support. The surface layer contains a polymer including, as monomer units, a first monomer having a polymerizable group and an aliphatic ring, a second monomer having a polymerizable group and a fluorine atom, and a third monomer having 4 or more polymerizable groups.

Endless belt with monomer having aliphatic ring

An imaging system includes: an endless belt, a tensioning member, a heating member, a pressing member, a cleaning member. The endless belt conveys a printing medium. The tensioning member tensions the endless belt. The heating member heats the endless belt. The pressing member presses the endless belt against the heating member. The cleaning member is located outside the endless belt, between the tensioning member and the heating member, and presses the endless belt inwardly.

Imaging system with cleaning member for endless belt

An imaging system includes a heating device, a conveyor belt including a surface layer located on an outer surface of the heating device to receive a printing medium, and a cooling device to cool the surface layer after the conveyor belt passes along the outer surface of the heating device. The surface layer includes a temperature sensitive material to vary an adhesive force of the conveyor belt with respect to the printing medium in response to a change in temperature of the surface layer. The adhesive force increases in response to an increase in temperature of the surface layer.
