Durable electrophotographic prints

A method for forming durable duplex images on both sides of a receiver member, said durable duplex images made on a receiver member having thereon a durable toner image on one face thereof, and a pre-gloss toner image on the opposite face thereof, said pre-gloss toner image formed from toner particles, said pre-gloss toner image having at least a portion thereof in which at least the outermost toner is made from UV-curable toner, a transport web having a smooth surface and transparency to UV radiation, wherein an input member including said pre-gloss toner image on said receiver member is movable in non-slip association with said transport web through a plurality of processing zones, with said outermost toner in direct contact with said smooth surface of said transport web, said method including the steps of:

• moving said input member with said transport web through a heating zone to melt toner such that at least said outermost toner is heated to a molten state so as to flow;
• with said molten state being maintained, moving said receiver member with said transport web into an exposure zone, and curing at least said outermost toner which contacts said smooth surface of said transport web in said exposure zone by a flux of UV radiation, said molten state being maintained during said curing, said curing causing crosslinking of at least said outermost toner, thereby forming a crosslinked fused toner image on said face of said receiver member;
• moving said receiver member with said transport web out of said exposure zone and through a cooling zone so as to cool said crosslinked fused toner image to a temperature below a glass transition temperature of any said UV-curable toner included in said crosslinked fused toner image;
• and
• moving said receiver member with said web through a separation zone such that said receiver member, bearing said crosslinked fused toner image, is separated from said transport web, thereby producing as an output member said durable duplex image glossed on both sides of said receiver member.

Glossing apparatus producing from a toner particle image receiver member an output member, said output member including a durable toner image, said glossing apparatus comprising:

• a receiver member transport web movable along a transport path, said transport web having transparency to UV radiation and a smooth surface, and a surface opposite said smooth surface;
• a heating zone, associated with said transport path, said heating zone including a heating mechanism having a controllable source of heat for melting at least said outermost toner of a toner image on said receiver member;
• an exposure zone, associated with said transport path downstream of said heating zone, said exposure zone including of a source of UV radiation;
• a cooling zone, associated with said transport path downstream of said exposure zone, said cooling zone including a cooling mechanism for cooling said transport web;
• a separation zone, associated with said transport path downstream of said cooling zone, said separation zone including a separation mechanism for separating said receiver member from said transport web;
• said receiver member selectively in operative engagement with said transport web such that said outermost toner of said pre-gloss toner image contacts said smooth surface of said transport web, in non-slip fashion, as said receiver member is transported by said transport web through said sequential heating, exposure, cooling, and separating process zones;
• wherein:
• in said heating zone, at least said outermost toner in contact with said smooth surface is heated to a molten state so as to flow;
• in said exposure zone, said outermost toner, a flux of UV radiation is emitted by said UV radiation to crosslink at least said outermost toner, thereby forming a crosslinked fused toner image on said face of said receiver member;
• in said cooling zone, said crosslinked fused toner image is cooled to a temperature below a glass transition temperature of any said UV-curable toner included in said crosslinked fused toner image;
• and in said separating zone, said receiver member is separated from said transport web so as to result in an output member including said durable glossed toner image on said face.
