Abstract: The present invention relates to a method and a device for displaying letters, images, etc. as well as a displaying medium used therefor, by which a display medium obtained by superposing a photoconductive layer, in which microcapsules are dispersed on a substrate. The microcapsules enclose a liquid crystal material which transitions between a transparent state and an opaque state by the application of an electric field. The substrate has a conductive surface so that charging of the surface causes the microcapsules to become transparent. An electrostatic latent image is formed on the surface of the displaying medium by irradiating selectively the surface with light. An AC electric field is applied to the displaying medium in order to make the microcapsules opaque at the position corresponding to the place, where the electric field is made disappear thereby making the latent image visible.

Abstract: A printer according to this invention comprises a latent image supporter having an endless belt shape and provided with separate image-forming regions, and a developing unit capable of independently supplying toners of different colors onto latent images formed on the latent image supporter. With the above arrangement, latent images for different colors are formed in the respective image-forming regions of the latent image supporter. Toners of the individual colors are then supplied to the respective latent images, thereby forming toner images of the respective colors. The toner images are transferred onto a sheet to provide an intended color mixing, and are then fixed by a fixing unit. The charges and toners remaining on the surface of the latent image supporter are removed by a static eliminator and a cleaner, respectively, so that the belt becomes ready for the next printing cycle.
