ABSTRACT:
A method and apparatus for the development of an electrostatic image on a recording surface by supplying liquid developer comprising positively or negatively charged toner particles dispersed in an electrically insulating non-polar carrier liquid to a developing zone where increments of the electrostatic image are succesively developed by attraction or toner particles to a recording layer, e.g., photoconductive coating (3), in a distribution depending on the distribution of charges forming said electrostatic image, wherein the liquid developer is supplied, e.g. with ink-jet (7), to the developing zone so that in course of the period over which the development of the complete electrostatic image takes place, said developer is made available at that zone in a distribution pattern which constitutes a lower resolution version of the electrostatic image to be developed, each increment of said pattern being brought directly opposite the corresponding increment of the electrostatic image.
