Abstract
Abstract A heat and pressure fuser apparatus (F, 54, 76) for fixing toner images to a substrate is characterized by the fact that silicone oil release agent material, which is usually required for such devices, is unnecessary. The fuser member which contacts the toner images comprises an outer layer (68, 82, 88, 105) of solid abhesive (anti-adhesive) material capable of retaining this property without degradation over the operating life of the apparatus. The fuser member is so constructed that the abhesive coating contributes to the formation of the nip (70, 92, 108) between it and a backup roller (72, 106).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
103 words
Heat and pressure fuser apparatus (F) for fixing toner images to a copy substrate, said apparatus comprising: a fuser member (54, 76, 86, 100) comprising a metal substrate (64, 78, 88, 101) coated with a solid abhesive material (68, 82, 90, 105); means (74, 80, 102, 110) for elevating the surface temperatue of said fuser member and a backup member (72, 106) adapted to be pressure engaged with said fuser member thereby to form a nip (70, 92, 108) between the two members, said fuser member being deformable by said backup member whereby said fuser member contributes to the formation of said nip
Claim 2
Dependent Claim
103 words
Heat and pressure fuser apparatus (F) for fixing toner images to a copy substrate, said apparatus comprising: a fuser member (54, 76, 86, 100) comprising a metal substrate (64, 78, 88, 101) coated with a solid abhesive material (68, 82, 90, 105); means (74, 80, 102, 110) for elevating the surface temperatue of said fuser member and a backup member (72, 106) adapted to be pressure engaged with said fuser member thereby to form a nip (70, 92, 108) between the two members, said fuser member being deformable by said backup member whereby said fuser member contributes to the formation of said nip
