  • Method and apparatus for developing electrostatic images
    Patent number: 5752142
    Abstract: A method and apparatus to develop electrostatic images using a mist which is substantially water and a colorant. Mist is transported from a generation station to a development station via a development electrode. Unused mist may be recycled or extracted. The mist may be size classified before development so that a consistent and desired resolution is obtained. Classification by size may be achieved by passing the mist in an arcuate path from the generation station to the development station.
