Abstract

A method is provided for transferring electrostatically charged thermoplastic toner particles having a particle size less than about 8 micrometers from an element to a receiver within a transfer zone. The receiver is heated and contacted with the electrostatically charged toner particles on the element at a temperature sufficient to adhere the particles to one another at their points of contact, but insufficient to cause the toner particles to flow into a single mass. An electric field tending to force the charged toner particles toward the receiver is simultaneously applied to the transfer zone. The receiver is subsequently separated from the element.
