Abstract
A fusing apparatus for fusing toner images onto a substrate. The fusing apparatus has a generally cylindrical pressure roller, a fuser roller, and a device for applying toner release oil to the surface there of. The fuser roller further includes a first length portion that has a generally cylindrical outer shape for contacting the pressure roller to form a fusing nip through which the substrate can be moved. In order to prevent damage to the surface of the fuser roller, the fuser roller includes a second length portion which lies towards an end of the fuser roller away from the fusing nip and has a generally conical outer shape for preventing contact between the fuser roller and pressure roller.
