The toner display by an electrical movement of conductive toner has been investigated. The display device is the sandwich type cell structure that is enclosed in two transparent electrodes coated by the charge transport layer. The conductive toner and white particle are been built-in in this cell. The charge transport layer acts on the both of hole injection from the electrode to conductive toner and insulating layer to keep the conductive toner on electrode. The toner display is a reflective display based on an absorption and scattering of ambient light at image and non-image area, respectively. In this paper, the response time of the toner display is measured by using the photon counting technique. The value of response time is about 1 msecond. The response time of toner display depended upon applied voltage.
