ABSTRACT:
A release agent (i.e. silicone oil) management system including a metering roll supported for contact with release agent material contained in a sump. The metering roll contacts a donor brush which, in turn, contacts one of a pair of fuser roll member. The donor brush comprises a rigid core having a non-woven felt layer adhered to the core. The felt layer provides a soft, nip forming layer. The felt layer is covered with a woven tube of Nomex to reduce the loss of loose fibers from the Nomex material. An oil barrier layer is provided between the Nomex tube and the felt layer for preventing or minimizing oil penetration into the oil permeable nip forming felt layer.
