ABSTRACT:
A release agent management system including a metering roll supported for contact with release agent material contained in a sump. The metering roll also contacts a donor brush structure which, in turn, contacts a heated fuser roll member.
The ends of the brush structure are provided with a pair of friction devices which contact the surface of the heated fuser roll member and do not contact the metering roll. Thus, the donor brush structure and the heated fuser roll member are frictionally coupled so that positive rotation of the heated fuser roll member imparts rotation to the donor brush structure.
