Electrically conductive toner powder for image development in electrostatic, electrophotographic or magnetographic image-forming processes.

摘要

An electrically conductive toner powder, the separate particles of which contain thermoplastic resin, additives conventional in toner powders, such as colouring constituents and possibly magnetically attractable material, and an electrically conductive protonised polyaniline complex. The protonised polyaniline complex preferably has an electrical conductivity of at least 1 S/cm. The conductive complex can be distributed over the volume of the toner particles or be present in a polymer-matrix at the surface of the toner particles.
