Claim 1
Independent Claim
211 words
A method of non-electrostatically transferring dry toner particles which comprise a toner binder and which have a particle size of less than 8 micrometers from the surface of an element to a receiver which comprises a substrate having a coating of a thermoplastic polymer on a surface of the substrate characterized in (A) contacting said toner particles on said surface of an element which has a surface layer which comprises a film-forming, electrically insulating polyester or polycarbonate thermoplastic polymeric resin matrix and a surface energy of not greater than 47 dynes/cm with said thermoplastic polymer coating on said receiver wherein said thermoplastic polymer is a thermoplastic condensation polymer having a Tg which is less than 10°C above the Tg of the toner binder and the surface energy of said thermoplastic polymer coating is 38 to 43 degrees/cm; (B) heating said receiver to a temperature such that the temperature of said thermoplastic polymer coating on said receiver during said transferring is at least 5°C above the Tg of said thermoplastic polymer; and (C) separating said receiver from said element at a temperature above the Tg of said thermoplastic polymer, whereby virtually all of said toner particles are transferred from the surface of said element to said thermoplastic polymer coating on said receiver.
