Abstract
The intensity of development of latent images on dielectric receptor sheets in a liquid bath which contains a dispersion of toner particles and fills a vessel between two electrodes one of which supports a sheet in such a way that the latent image faces the other sheet is regulated by measuring the current which flows between the electrodes in response to insertion of a fresh sheet between the electrodes, comparing the measured result with a preselected reference value, and evacuating the bath from the vessel to thereby terminate the development when the ratio of measured result to the reference value is one-to-one or another preselected ratio.
