Abstract
A toner characterization cell used to determine characteristics of insoluble particles in a liquid medium. First and second electrode are spaced apart and an electric field is applied between the electrodes and a displacement current is measured. Optical density measuring devices measure the change in optical density in the cell adjacent each electrode. The characteristics are determined from the displacement current and the change in optical density. The characterizing feature may be particle mobility. The invention also relates to a method of determining the characteristics.
