Abstract
A technique for detecting the toner solids concentration of a liquid toner uses electrostatic sensing and avoids reliance on optical transmission paths, which tend to clog and lead to undertoning or overtoning. The toner solids concentration is instead detected by measuring the residual electric potential of a developed area on an image bearing member. The residual electric potential has been discovered to correlate well with the toner solids concentration.
