Abstract
A method is provided for non-electrostatically transferring dry toner particles which comprise a toner binder and have a particle size of less than 8 micrometers from the surface of an element to a receiver. The element comprises a conductive substrate and a surface layer which contains an electrically insulating polymeric binder resin matrix which comprises a crystalline side chain polyester or a block copolyester or copolycarbonate having a crystalline side chain polyester block and the receiver comprises a substrate having a coating of a thermoplastic addition polymer on a surface of the substrate in which the Tg of the polymer is less than approximately 10.degree. C. above the Tg of the toner binder. The method involves contacting the toner particles with the receiver which is heated to a temperature such that the temperature of the thermoplastic polymer coating on the receiver substrate during transfer is at least approximately 15.degree. C. above the Tg of the thermoplastic polymer whereby virtually all of the toner particles are transferred from the surface of the element to the thermoplastic polymer coating on the receiver substrate and the thermoplastic polymer coating is …
