Abstract
A method for operating electrographic printers or copiers uses toner particles of two different colors applied to a toner image carrier by at least two developing units. A force field is applied to at least one section of the travel path of the toner particles from a toner container to the toner image carrier to cause the toner particles to be carried in the direction of the toner image carrier. Changing the force field causes an interruption of the transfer of the toner particles with the developer stations are in a rest position.
