Abstract
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.
