Abstract:
1. A fuser member comprising a substrate; an outer layer covering the substrate; and a release coating on the outer layer comprising a release fluid for coating the outer layer, the release fluid further 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), further wherein the release fluid is a toner release fluid and the toner release fluid chemically reacts with fillers present on the outer layer so as to reduce surface energy of the fillers to provide release of toner from the outer layer while said chelating agent substantially prevents precipitation of toner process byproducts on the outer layer by binding to metal ions present in the toner.
