Abstract
Roll-type presses or pressure developers include a pressure roll in which one of the load bearing and transmitting materials is a carbon fiber and epoxy composite. The pressure roll has an outer metal tubular sleeve which is filled or substantially filled with a composite material. In one form, an axially central loading shaft is employed and is bonded to the composite material. The material may be tapered from a central loading region on the shaft and outwardly toward the open ends of the sleeve. In another embodiment, the composite material itself forms the support shaft for the roll.
