PURPOSE:To prevent the turbulence of the picture image by dissolving a substance capable of forming a transparent film into a solvent substantially non- dissolving a color toner composition. CONSTITUTION:The substance capable of forming the transparent coating film is dissolved into the solvent substantially non-dissolving the color toner composition. The color toner composition is comprised a binder resin, a coloring matter and optionally, an electric charge controlling agent which are compounded in the color toner. The solvent substantially non-dissolving the color toner composition is comprised the solvent such as a lower alcohol, ethylether of ethylene glycol, cyclohexanol, acetic acid, solely or a mixture thereof for the resin such as styrene, acryl, polyester and epoxy resins which are usually used to the color toner. The substance capable of forming the transparent film is dissolved in the solvent, thereby reproducing a good color of the color toner image in the projection, and effectively preventing the peeling and discoloring of the color toner image. |
