摘要

A fusing assembly for use in an electrostatographic imaging apparatus includes a release agent donor member having a conformable donor surface comprising the crosslinked product of at least one addition curable vinyl terminated or vinyl pendant polyorganosiloxane having the formula:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="55" wi="123" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" /></Chemistry> where A, B and R are methyl or vinyl provided the vinyl functionality is at least 2,0 < <Underline style="single">s</Underline> ≦ 350 < r + s < 2700, a polyfunctional silicone hydride crosslinking agent, a crosslinking catalyst and finely divided filler. In a preferred embodiment the conformable donor surface comprises a rotatable cylindrical roll with a high coefficient of friction which is rotatably driven by frictional contact with a positively driven fuser roll. The release agent may be supplied from a sump by a release agent metering roll.
