Method and Arrangement For Inking Up an Applicator Element of an Electrophotographic Printer or Copier

摘要

In a method or system for generation of a toner image layer with a preset layer thickness on a surface of a photoconductor, the two-component mixture of electrically charged toner particles and carrier particles is directed on an auto-surface of a roller adjacent a surface of an applicator element to be inked. At least a portion of the toner particles is transferred onto the surface of the applicator element. An electrical field is generated that exerts at least one force on a portion of the electrically charged toner particles between the roller and the applicator element. A strength of the electrical field is varied to adjust a layer thickness of a layer of the toner particles transferred onto the surface of the applicator element and thus to adjust a thickness of the toner image layer on the photoconductor. A measurement arrangement detects a thickness of at least one region of the toner image layer inked on the surface of the photoconductor as a real value. The determined real value is compared with a desired value determined by a preset layer thickness, and a strength of the electrical field is controlled dependent on a deviation of the determined real value from the desired value.
