Abstract
A printing machine in which an image recorded on an electrostatic master is developed with liquid developer material and the excess liquid developer material eliminated therefrom. A meniscus is formed between a roll and the electrostatic master. The roll is adapted to remove the excess liquid developer material from the developed image. The meniscus is formed by electrically biasing the roll as the roll moves from a non-operative position remote from the electrostatic master to an operative position adjacent thereto.
