The printing technology that uses the toner, such as the electrophotography, is necessary for our life. However, the efforts for realizing a simpler mechanism are important because the electrophotography printing mechanism is complex. The mechanism has 6 processes. To decrease the processes is considered one of good approaches for realizing improvement. To control toner cloud by a pair of electrode has been proposed. As a fundamental data, the control characteristics of single aperture electrode are important. The single aperture has also a possibility of application. In this study, the toner cloud is generated between the aperture electrode and dented electrode by voltage application and the dependence of toner amount passing through the aperture on outer electric field is obtained. It is found that as the thickness of the aperture electrode increases, the range of the electric field of the state in which toner can not pass through becomes wide.
