And consequently, the temperature within the machine should be kept as low as possible.
  • one of the objects of this invention is to prevent the heat radicated from the drying-fixing device from badly affecting other processing devices and to improve the efficiency of drying the transfer paper.
  • Duct 21 is provided below the heat plate 7 and has a port 22 opened upwardly and within the port or inside of the duct, a suction fan is provided for suctioning the air from underside of the heat plate 7 and sending out the air from the machine.

Therefore, after the rear end of the transfer paper P is departed from the photosensitive member, much of the accumulated carrier liquid attaches over several millimeters width at the rear edge of the transfer paper as droplets, and consequently, said portion is most difficult to be dried, and in fact there is a case where the carrier liquid remains still in the form of droplets at said portion after the transfer paper is passed through the drying fixing device. As a result, the image quality is deteriorated by rubbing carelessly the liquid carrier, or each of the transfer papers is not regularly piled within the tray.
  • the phenomenon of producing said pool of the carrier liquid is not avoidable because of the transfer principle of the liquid developing system.
  • it is considered to elevate the temperature of the drying-fixing device or to increase the drying time, however, in the former case, excess heat is applied to the portions of the transfer paper other than said rear edge, and also the temperature of the machine itself is also elevated. And in the latter case, copy speed is decreased and the copier becomes bulky.
