Abstract

PURPOSE:To obtain scarcely breakable toner that is durable for repeated use collected after application for direct viewing or projection of an image without fixing after a static latent image of sensitive substance is developed producing real ball-like one component toner consisting magnetic substance, resin and dielectric. CONSTITUTION:Such a magnetic powder 2 as magnetitie, iron powder, etc. and thermal-setting resin such as water-soluble melamine resin 1 etc. are mixed thoroughly with water, and dielectric material 3 such as carbon black, etc. is added, and the mixture is further crushed and mixed to be dispersed liquid from which real ball-like toner particles are obtained by a spray device or the like. The static latent image on the dielectric substance is developed by using this, and after utilizing it for direct viewing or projection of an image, it is collected by bleeding from the dielectric and used repeatedly. Thus, the toner is obtained that is never be broken up or damaged on its dielectric substance or never generates a fog. Also, a resin solution contained CuI or the like 3, as dielectric material, is available on the toner that does not contain the above said carbon black to coat 4 its surface.
