Abstract

It is well known that mercapto functional polyorganosiloxanes and carboxy functional polyorganosiloxanes can be applied as release agents to fuser members. In U.S. Patent 4,011,362, metal substrates are coated with carboxy functional siloxanes to improve their release characteristics; and in U.S. Patent 4,029,827, polyorganosiloxanes having functional mercapto groups are applied to a heated fuser member in an electrostatic reproducing apparatus to form thereon a thermally stable, renewable, self-cleaning layer having superior toner release

It is well known that mercapto functional polyorganosiloxanes and carboxy functional polyorganosiloxanes can be applied as release agents to fuser members.

In U.S. Patent 4,011,362, metal substrates are coated with carboxy functional siloxanes to improve their release characteristics; and in U.S. Patent 4,029,827, polyorganosiloxanes having functional mercapto groups are applied to a heated fuser member in an electrostatic reproducing apparatus to form thereon a thermally stable, renewable, self-cleaning layer having superior toner release

properties for electroscopic, thermoplastic resin toners,

The present disclosure relates to the application of a class of release agents having sulfur-containing functional groups wherein the sulfur atom contains a replaceable hydrogen atom to a heated fuser member in an electrostatic reproducing apparatus. In preferred embodiments, these release agents are applied to bare metal fuser

members.

The release agents having sulfur-containing functional groups wherein the sulfur atom contains a replaceable hydrogen atom (may be attached to a hydrocarbon), a

polymeric hydrocarbon chain, or a polymeric siloxane. The sulfur-containing groups can be attached terminally or as branches. The backbones to which the sulfur- containing functional groups are attached, may be straight chained o...
