Toner coated with conductive polymer

The present invention relates to a toner comprising toner particles each comprising a core provided with a conductive surface layer containing a doped electrically conductive polymer. A toner of this kind is known from the pre-published Japanese Patent Application 3-100561. This toner, which is made up of a number of individual toner particles, can be used, for example, in an electrophotographic imaging process. By varying, for example, the thickness of the conductive surface layer, the resistance of the toner can be adjusted between 1 and 1*10 ohm*m. The toner resistance is practically independent of the ambient conditions, particularly the air humidity. A toner comprising separate toner particles each of which comprises a fixable core, the core being provided with a conductive surface layer containing a doped electrically conductive polymer and an intermediate layer, particularly a polymer-containing intermediate layer disposed between the surface layer and the core.
