Abstract
A toner powder comprising toner particles which carry on their surface and/or in an edge zone close to the surface fine particles of electrically conductive material consisting of fluorine-doped tin oxide. The fluorine-doped tin oxide particles have a primary particle size of less than 0.2 micrometer and a specific electrical resistance of at most 50 ohms.meter. The fluorine content of the tin oxide is less than 10% by weight, and preferably is from 1 to 5% by weight.
