Toner cloud beam is a novel toner-based printing method that employs a conductive toner. In this method, the toner beam is controlled by applying a pulsed voltage to a pair of aperture electrodes. It is important to determine the pulse control characteristics of the toner beam. Hence, this study experimentally investigates the dependence of dot formation on the electrode voltages and the relationship between the dot size and the pulse duration. An enlarged model with an aperture diameter of 0.5 mm is used to confirm that dots are formed directly on paper in less than 10^-4 s. The toner motion is characterized by a toner velocity of ∼1-2 m/s and a toner motion relaxation time of ∼3×10^-4 s.
