Abstract: A record processor employing a novel developing system, toner module and method in which a quantity of toner fluid is held adjacent to an electrostatic latent image on a film, in a substantially quiescent state, for a sufficiently long period to insure migration and adherence of toner particles to the image, is disclosed, wherein a set small quantity of fluid is drawn into a development chamber formed adjacent to the film which chamber is sized and shaped so as to facilitate the fluid reaching a relatively quiescent state quickly and which fluid is held in the chamber by a natural meniscus dam at a sharp edge formed across the flow path of the toner.
