Method for operating printer for printing recording medium with toner particles, involves transporting recording medium through printing gap between transfer roller and counter print roller, where transfer roller carries toner particles

摘要

The method involves transporting the recording medium (10) through a printing gap (16) between a transfer roller (12) and a counter print roller (14). The transfer roller carries toner particles on its surface in a distribution corresponding to the print images to be printed having an electric charge of a predetermined polarity. The toner particles provided in the printing gap are transferred from the transfer roller to the surface of the recording medium.
