A contact fusing apparatus comprising a heated roll structure cooperating with a pressure roll structure to form a nip through which support material carrying toner images thereon is moved with the toner images contacting the heated roll structure. The contact fuser is characterized by the provision of stripping means for insuring removal of the support material from the heated fuser roll and a roller structure interposed between the stripper means and the nip which roller contacts the support material to thereby restrain the material while the leading portion of the material is being stripped from the heated roll structure. The result of stripping while restraining is to minimize the degree of curling of the copy paper.

Fixing device for use in electrophotographic copying machine

A fixing device in an electrophotographic copying machine, wherein stripping members each being in contact with the surface of a heating roll 21, and conveying rolls which serve to convey a support material while the latter being held therebetween, are positioned on feedout sides of the heating roll for thermally fixing a thermoplastic material on the image support material and a pressure roll characterized in that said conveying rolls have their peripheral speeds higher than that of said heating roll.
