PURPOSE:To provide a multi-color printing device capable of being simplified and miniaturized and allowing multi-color printing to be performed at a low cost. CONSTITUTION:An endless film sheet 21 is circulatively conveyed by a driving roll 38. A conveying path is provided with an electrifying head 24, a color head 23, a cyan toner vessel 25, a magenta toner vessel 26, and an yellow toner vessel 27. An electrostatic latent image of one color is formed by the color head 23, the toner of the corresponding color is fed, and development is conducted in this color. The developed toner is heated and melted by an intermediate heating head 29, and development for a toner of another color is repeated. When the development for the color image is completed, an electrostatic latent image in black and white is formed by an electrification head 34 and a black- and-white head 33, a black toner is fed from a black toner vessel 28 for development, and a recording paper 22 is held between a heating head 30 and a fixing roll 31 for thermal transfer. |
