Controllably conductive polymer compositions may be used in electrophotographic imaging developing systems, such as scavengeless or hybrid scavengeless systems or liquid image development systems. The conductive polymer compositions includes a charge-transporting material (particularly a charge-transporting, thiophene-containing polymer or an inert elastomeric polymer, such as a butadiene- or isoprene-based copolymer or an aromatic polyether-based polyurethane elastomer, that additionally comprises charge transport molecules) and a dopant capable of accepting electrons from the charge-transporting material. The invention also relates to an electrophotographic printing machine, a developing apparatus, and a coated transport member, an intermediate transfer belt, and a hybrid compliant photoreceptor comprising a composition of the invention.

Controllably conductive polymer compositions for development systems

An apparatus for determining charge density and mobility in a liquid solution having electrically charged particles therein. The apparatus includes an electrode, and a dielectric member having a first surface situated opposite the electrode for providing a volume therebetween in which a sample of the liquid may be placed. A fixed bias voltage applied to the electrode to produce an electrical current flow through the liquid solution and the dielectric member. A device coupled to the dielectric member, measures the electrical current as a function of time to provide a measure of voltage decay across the liquid solution. The voltage decay corresponds to the charge density of the liquid solution.
