A method and apparatus for printing ceramic or glass flat substrate, wherein a fusible powder is applied to an image forming medium in order to form an image thereon which is transferred to an intermediate medium, and the powder image formed on the intermediate medium is brought into contact with the substrate in a contact zone, the ceramic or glass substrate being heated in a pre-heating device before the contact zone to a temperature of at least 60.degree. C., and wherein the intermediate medium in the contact zone is heated to a temperature of at least 100.degree. C.

Method and apparatus for decorating ceramic and glass substrates and the

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