description	A fuser apparatus for heat fusing toner images to print substrates, comprising an elongated fuser roll (34) and an elongated pressure roll (36). The pressure roll is supported for pressure engagement with the fuser roll to form a nip (65) therebetween adapted to receive substrates (82). An oil impregnated web material (77) and an elongated pinch roll (79) are provided. The pinch roll (79) has an outer surface mounted against the web material (77) to urge the web material into contact with the fuser roll (34) to apply release material to the fuser roll. The outer surface of the pinch roll (79) is of an open celled foam material, and is of greater diameter in the central portion of the roller than at the end portions. The pinch roll thus applies a greater pressure to the web (77) over the central portion than at the end portions, and therefore applies more release material over the central portion of the fuser roll than over its end portions.
