Abstract:
1. An arrangement for inking in an electrophotographic printer or copier, comprising: a magnetic roller having a rotatable magnetic roller sleeve having a circumferential surface to which a two-component mixture comprising toner particles and ferromagnetic carrier particles adheres; an applicator element having a circumferential surface to be inked with toner particles and past which the two-component mixture adhering to the circumferential surface of the magnetic roller is guided to produce a toner layer on the circumferential surface of the applicator element; the magnetic roller having a magnetic rotor which comprises magnetic elements and which is arranged inside said magnetic roller sleeve; the magnetic elements being substantially uniformly distributed over a circumference of the magnetic rotor; a rotary axis of the magnetic rotor being an axis parallel to a rotary axis of the magnetic roller sleeve; and at least one drive unit which drives both the magnetic rotor and the magnetic roller sleeve and which moves the magnetic rotor and the magnetic roller sleeve relative to one another.
