Abstract
Disclosed is a toner image fixing device that is capable of changeably setting sheet separating portions in contact with or apart from the cylindrical surfaces of corresponding fixing rollers in accord with the resiliency of recording material to surely prevent a recording material from wrapping round the fixing rollers and being jammed between the rollers and capable of minimizing the frequency of contacting the separating portions with the fixing roller surfaces to obtain an increased quality of a toner image fixed on the recording material and elongate the service life of the fixing rollers.
