6 Claims

1. A release fluid for coating a fuser member layer comprising polymeric functional polydimethylsiloxane (PDMS) having amino or mercapto functional groups, wherein the mole ratio of amine to silicon atoms is from about 0.03% to about 0.2% and the mole ratio of mercapto groups to silicon atoms is from about 0.05% to about 0.5%, and a metal chelating agent selected from the group consisting of meso-tetraphylporphyrin (TPP), N-(hydroxyethyl) ethylene-diaminetetraacetic acid (HEDTA), sodium diethanolglycine (EIMA), dimercaprol (oil soluble), and amino-ethylethanolamine (AEEA), wherein the release fluid is a toner release fluid and further wherein the toner release fluid chemically reacts with fillers present on the fuser member layer so as to reduce surface energy of the fillers to provide release of toner from the fuser member layer while said chelating agent substantially prevents precipitation of toner process byproducts on the fuser member layer by binding to metal ions present in the toner.
