Abstract

In a method to remove toner deposits on a surface of a cleaning element, electrically charged toner particles are transferred from a transfer element surface to a photoconductor. On the cleaning element, untransferred, electrically charged toner particles as residual toner from the transfer element surface are received. Electrically charged toner particles on the cleaning element are directed past an electrode arrangement arranged at a distance from the surface of the cleaning element. An alternating electrical field is generated which acts on the toner particles to loosen them. The toner particles remaining on the surface of the cleaning element are brought into contact with a mixture of carrier particles and toner particles during further transport along a transport direction of the cleaning element.
