Abstract
An apparatus and method for producing an electrostatic image is disclosed. A thin layer of hydrophobic particles is coated on the surface of the charge bearing member which can be a photoconductor or a dielectric. The hydrophobic particles may also be used on the developer roller which applies the toner. A liquid toner made substantially of a hydrophilic liquid, such as water, and suspended pigment binders is used. The invention is applicable to both one and multiple color systems.
