Abstract
A basic research is being carried out in our laboratory on transport of particles in electrostatic traveling field to utilize it for laser printers. A particle conveyor was constructed. it consisted with parallel electrodes covered with insulating film on an acryl substrate. Traveling electrostatic waves were four-phases and rectangular shape with amplitude up to 1,000 volts, generated by function generators and amplifiers. The following were clarified by the experiment and numerical investigation : (1) Particles were transported almost linearly with time and the rate was also linear with applied voltage but a threshold existed due to adhesion force. (2) The direction of particle transport did not always coincide with that of the traveling wave but partially changed depending on the frequency of the traveling wave.
