ABSTRACT:
A high speed electrostatic printing machine has a toner supply of a high viscosity highly concentrated liquid toner to a pick-up roller and then a metering roller. A doctor blade bears against the metering roller which bears against a development member with an interference fit. An image forming stage comprising an image carrying member having a surface adapted to retain an electrostatic latent image thereon with the development member engaging against the image carrying member with an interference fit to give a selected contact time therebetween. Then there is a development stage and a transfer stage. A carrier liquid displacement device acts upon the thin layer of toner on the development member to push toner particles in the thin layer towards the surface of the roller and to leave a carrier liquid rich layer on the outside of the thin toner layer.
