Abstract
The method of developing an electrostatic latent image contained on a surface comprising the steps of applying to a surface a dispersion in a first state wherein the flow properties of the dispersion are non-Newtonian and wherein the dispersion consists of a liquid phase and of a solid phase comprising flocculated electroscopic marking particles forming a matrix sufficiently strong to prevent extraction of individual electroscopic marking particles from the matrix and applying to the dispersion a shear stress of sufficient magnitude to convert the dispersion from the first state to a second state wherein the flow properties of said dispersion become Newtonian and wherein said solid phase is deflocculated.
