<p>ROLL FUSER A xerographic reproducing apparatus comprising a roll fuser structure comprising a heated roll cooperating with a backup roll to form a nip through which copy substrates are moved with toner images contained thereon contacting the heated fuser roll to thereby tackify the toner for subsequent fusing to the copy substrate upon cooling of the toner. The roll fuser is characterized by the provision of a resilient outer layer which has a non-uniform surface which layer is applied to a rigid core having a non-uniform surface which is complementary to the non-uniform surface of the silicone rubber layer. The non-uniform surfaces allow the silicone rubber to have alternate thick and thin portions along the longitudinal axis thereof which portions set up a strain pattern on the roll surface as the surface moves through the nip such that the copy substrate which tends to adhere to the fuser roll is stripped from the roll as the strained portions of the rubber layer return to their normal shape after passing through the nip.</p> |
