ABSTRACT:
This invention provides foam-covered rolls comprising silicone foam layer over a metal core and a fluororesin film laminated over the foam layer. The cured foam layer is obtained by using as the blowing agent the hydrogen gas generated by the reaction of an organohydrogenpolysiloxane with a compound containing at least one hydroxyl group per molecule. The resultant rolls are very durable, highly toner-releasing and are free of creases on the roll surface. Using the fabrication method that constitutes one embodiment of the present invention, foam covered rolls can be produced very efficiently.
