Abstract

In a device and method for lifting magnetizable carrier particles from a mixture of toner particles, a cover of a collecting element interface device is arranged such that it can be rotated around a stator with a magnet. The cover comprises a spiral that, given rotation of the cover, conveys the carrier particles in an axial direction.
