Abstract

An apparatus for the liquid development of an electrostatic latent image having at. least one pair of rollers is given. Positioned between a developing roller 11 and its counter roller 13 is a latent image bearing surface 10 whose face is spaced from the developing roller 11 by flange 12 which maintains a predetermined spacing '~d~between the developing roller and the developing surface, When an image bearing substrate 12 is not present, flange 12 makes electrical con- tact with counter roller 13 biasing the system using energy source 30 such that liquid developer 15 from developer dis- pensing menTher 14 does not contaminate the counter roller 13.
