ABSTRACT:
A device and a method for developing an electrostatic latent image, which is located on a movable image carrier (1), using a non-conductive single-component toner. The device includes a toner feed device (3), in order to transport toner particles (5) from a toner reservoir (4) and charge them electrically, a rotationally mounted developing roller (2) to receive the charged toner particles from the toner feed device and to transport the toner particles which it holds into a gap between the developing roller and the image carrier, and a rotationally mounted doctor roller (6), which is arranged in the path of the toner particles from the toner feed device to the developing roller, to produce a uniform toner layer with a defined thickness on the developing roller. The surface of the developing roller (2) and the surface of the doctor roller (6) are separated from one another by a gap which is wider than the average diameter of the toner particles (5). In this manner, electrographic printing with high quality and at high speed is made possible.
