Abstract
A release agent composition for use in an electrophotographic process is disclosed. This composition includes a specifically-defined heat-stable silicone oil-silicone wax random copolymer. The copolymer has a melting point such that it is liquid on the hot fuser roll, but solidifies at room temperature on the printed page. A random silicone copolymer, in the form of a paste or pliable caulk, which is useful for sealing leaks in toner cartridges is also disclosed. Finally, the method for preparing these copolymers is disclosed.
