    • A transfer type ink jet printer having an ink jet head for ejecting droplets of ink in which charged coloring particles have been dispersed in a solvent in the form of insulating carrier liquid having a low dielectric constant, a transfer medium for carrying and moving an ink image formed of ink droplets ejected from the head, and a pressure roller for transferring the ink image written to the transfer medium to a recording medium. By temporarily fixing the charged coloring particles in the ink image onto the transfer medium until the ink image is led to the transfer means after the ink image is formed on the transfer medium, good and high-speed image printing has been made possible without vapor generation, so that an excellent image free from any printing pattern is available at a low transfer pressure. There is also provided a unit for removing a solvent by making the solvent on the transfer medium with the charged coloring particles temporarily fixed by the means for temporarily fixing the particles contact water or a surface active aqueous liquid agent.
    • 一种转印型喷墨打印机,具有用于喷射墨滴的喷墨头,其中带电着色颗粒已经分散在具有低介电常数的绝缘载体液体形式的溶剂中,用于承载和移动墨图像的转印介质 由从头部喷出的墨滴形成;以及加压辊,用于将写入转印介质的油墨图像转印到记录介质上。 通过将墨水图像中的带电着色颗粒临时固定到转印介质上,直到在转印介质上形成油墨图像之后将油墨图像引导到转印装置上,才能实现良好的高速图像印刷 ,使得在低转印压力下可以获得没有任何印刷图案的优异图像。 还提供了通过在转印介质上制造溶剂,通过用于临时固定颗粒接触水的装置或表面活性含水液体试剂暂时固定带电着色颗粒来除去溶剂的单元。
