Toner control is important in electrophotography and also a new toner printing. The new printing technology, which utilizes conductive toner, is proposed. In the technology, toner cloud is generated by voltage application and toner beam is extracted from the toner cloud to a receiver, such as paper. To realize the new technology, it is necessary to generate toner cloud uniformly over a certain width. Toner cloud transport in long ovally dented electrode is investigated. The speed of toner cloud is observed by a digital camera and the speed dependences on applied voltage, toner amount, and distance between electrodes are obtained. The possible mechanism of toner cloud transport to long oval direction is discussed.
