A system and method for recovering charge-bearing solid pigment particles from a fluid dispersant in a liquid toner, wherein the system includes a particle-accumulating surface spaced apart from a complementary electrically biased electrode surface to define a channel therebetween. The channel has a mouth in gravity-feed relation to an outlet. Liquid toner is introduced at the mouth to cause flow within the channel. The bias of the electrode, however, sets up an electric field in the channel directing charge-bearing solid pigment particles away from the electrode surface so that only substantially particle-free fluid dispersant reaches the outlet. A slime rich in charge-bearing solid pigment particles collects on the particle-accumulation surface which is moved in a direction opposite of toner flow. At a location remote from the electrode, the solid pigment particles are removed from the particle-accumulating surface and are stored for later remixing with the fluid dispersant to form fresh toner.
