ABSTRACT:
A developing station for an electrostatic copier which station includes a magnetic roller connected to a rotary drive and disposed within a stationary sleeve made of a non-magnetizable material. The magnetic roller is adapted to receive a powdered toner, especially a single-component toner along its outer circumference. The stationary sleeve and roller are disposed so that an area of the outer circumference of the stationary sleeve and roller is located opposite an image carrier or an intermediate image carrier which is transported through the developing station past the magnetic roller. At least an outer surface of the sleeve is formed of an electrically insulating material with an insert or covering of an electrically conducting material being provided in the area of the sleeve which is opposite the image carrier or the intermediate image carrier.
