ABSTRACT:
An electrostatic printing method for developing an electrostatic latent image on a recording member by first developing the image by the "electrostatic developing" method in which a liquid developer comprising an insulating liquid vehicle and a solid colorant is electrostatically attracted and applied only to the electrostatic latent image, and then further developing the image, by "liquid developing" in which an insulating liquid miscible with the vehicle used in the electrostatic developing step and containing substantially no coloring matter is applied to the image and non-image areas on the recording member, whereby some of the solid colorant attracted to the electrostatic image is charged and migrates to any image portion not developed by the electrostatic developing step.
