A method of toning the latent image carried by the photoconductive surface of an electrophotographic film in which a liquid suspension of toner particles is flowed or streamed substantially simultaneously uniformly against said surface over all said surface in a direction normal thereto from a source spaced from the surface and the excess or remanent toner suspension is removed from the surface thereafter without displacing said source or moving the film.The toner particles are biased with a d.c. bias voltage of a polarity the same as the electrophoretic surface charge of the toner particles to enhance particle movement toward the photoconductive surface.
