Abstract
A process of producing a liquid image, wherein an insulating material bearing an electrostatic charge pattern detectable at its surface is developed by wetting with a developing liquid according to such charge pattern and in which process developing liquid is brought substantially uniformly in close proximity to or in contact with the material with at least two developing liquid applicator means, which are disposed in succession along the path followed by the material and which supply developing liquid to the material in such a way that the liquid image is gradually built up by amounts of liquid offered by such successive applicator means.
