To provide a process for producing a glass plate having an electric conductor pattern excellent in adhesion with the surface of the glass plate, whereby it is not required to have a screen ready for every model and adjustment to desired electric heating performance and antenna performance is easy, and a toner for electronic printing therefor. A toner for electronic printing, which comprises toner matrix particles comprising conductive fine particles, a heat decomposable binder resin and glass frit, and heat decomposable organic resin fine particles attached on the surface of the toner matrix particles, wherein the heat decomposition temperature of the organic resin in the heat decomposable organic resin fine particles is lower than the heat decomposition temperature of the heat decomposable binder resin. A process for producing a glass plate having an electric conductor pattern, which comprises using such a toner to form a pattern of the toner on a surface of a glass plate by an electronic printing system, then heating the glass plate having the pattern of the toner formed on its surface at a predetermined temperature to convert the pattern of the toner to a pattern of an electric conductor.
