  • Roller for supporting an imaging belt in a printing apparatus
    Patent number: 7151905
    Abstract: A belt photoreceptor in a xerographic printer is entrained on a roller formed from a set of discs. Each disc defines an outer circumference and a flexible main portion. The outer circumferences of a set of discs effectively form a single outer surface of the roller. The discs are flexible and can move against each other, to allow stabilization of the photoreceptor belt, but are in sufficient contact with one another to enable heat to be distributed evenly across the roller.
