Dry toner technology remains the dominant technology in electrophotography and recent improvements in print speed and image quality have helped to secure this position. However, there has been a resurgence of interest in liquid toner technology. Recent advances in toner chemistry and liquid electrophotographic processes have opened new opportunities to exploit the inherent advantages of liquid systems. This paper discusses recent developments in liquid toner chemistry and processes that have the potential to effect substantial reductions in print cost, increases in print speed and reductions in the environmental impact without sacrificing image quality or the other inherent advantages of liquid systems.
