PURPOSE:To eliminate the necessity of heating and the irregularity of paper sizes caused by the difference in the degree of shrinkage by allowing a microcapsule filled with coloring agent to adhere with a developer-coated paper and destructing the microcapsule with a pressure roller and then allowing the paper to be colored. CONSTITUTION:A laser exposure part 3 performs line scanning while turning laser beams on/off so as to allow the allow the laser beam to correspond to printing dot data and an electrostatic latent image is formed on a photosensitive drum 1. The electrified microcapsule 41 filled with the coloring agent is brought into contact with the coloring photoconductive face of the photosensitive drum 1 in a fixing part 4. An image formed with the microcapsule 41 is transferred on the developer applying paper 8. The microcapsule 41 is destroyed by pressing the paper 8 to allow the coloring agent and the developer to be reacted with each other, and then, printed data is colored. Thereby, a heating process is removed from a printing process and the shrinkage of the paper 8, etc., is prevented. |
