Abstract

An apparatus for glossing a developer sheet is provided. The developer sheet has a thermoplastic developer resin on the surface thereof wherein the thermoplastic developer resin is capable of forming a film which imparts gloss upon the application of heat thereto. In the process, an arched plate is heated to a temperature sufficient to cause the thermoplastic developer resin to coalesce. The arched plate has a heat transfer limiting blanket thereon to maintain the flatness of the developer sheet. The developer sheet is fed between the convex side of the heated arched plate and a belt held snugly against the plate. The belt is driven so as to move the developer sheet over the heated arched plate.
