Transported medium heating-liquid-barrier toner fixer

A toner fixing system for fixing toner onto a receiver medium, the toner having a toner glass transition temperature, comprising:

• a reservoir containing a heating liquid;
• a liquid-heating system for warming the heating liquid in the reservoir to a temperature greater than the toner glass transition temperature;
• a rotatable liquid-blocking barrier with an inner surface and an outer surface;
• and
• a media-transport system for transporting the receiver medium along a transport path in which the receiver medium contacts the liquid-blocking barrier so that the receiver medium is brought into contact with the outer surface;
• wherein the liquid-blocking barrier and the reservoir are arranged so that an entrained portion of the receiver medium passes through the reservoir, the entrained portion is submerged in the warmed heating liquid, the heating liquid is brought into contact with the inner surface of the liquid-blocking barrier, and heat is transferred from the warmed heating liquid to the toner, whereby a temperature of the toner is raised to a level above the toner glass transition temperature.
