Abstract
A method for selectively removing magnetically attractable toner particles from an image-forming device and an image-forming device for performing the same are provided. The image-forming device includes a cleaning magnet system, configured to provide an activatable second magnetic field. The method includes a step of switching the image-forming device into a cleaning mode, the cleaning mode including the steps of stopping the toner supply to the image-recording medium, rotating the rotatable sleeve in a second direction, opposite to the first direction, such that the magnetically attractable toner particles are transported out of the developing zone towards the cleaning magnet system, and activating the second magnetic field so as to remove the transported magnetically attractable toner particles from the rotating rotatable sleeve of the developing element.
