Toner cloud beam (TCB) is a novel toner-based printing method that employs conductive toner. Toner dots are formed directly on paper in the TCB method. The toner beam is controlled by applying a pulsed voltage to a pair of aperture electrodes. The pulse control characteristics of the toner beam are important in the TCB method. The dot formation dependence on the electrode voltages is investigated experimentally and the relationship between the dot size and the pulse duration is obtained. An enlarged model with an aperture diameter of 0.5 mm is used to confirm that dots are formed in less than 10−4 s. The toner speed at a toner cloud generation voltage of 550 V is estimated to be 4.1 m/s.
