ABSTRACT:
A liquid developer is prepared from a liquid electrostatic developer concentrate comprising up to 80% toner solids and a surfactant. The liquid electrostatic developer concentrate may be prepared by preparing a liquid electrostatic developer containing up to 20% toner solids; subsequently adding a surfactant to the liquid electrostatic developer; and concentrating the liquid electrostatic developer. The surfactant permits the easy redispersion of the toner solids at the time of use.
