CONSTITUTION:This toner is constituted by incorporating at least the binder and coloring agents into the toner in such a manner that the binder compsn. partly dissolves in water and lowers its viscosity. The regeneration processing of the paper recorded with the toner constituted in such a manner is executed by using a water-soluble resin for the binder and first loosening the pulp fibers of the recorded paper in water. Since the binder is water-soluble, the binder dissolves and disperses in the water in this stage. The regenerating and recycling of the paper are, therefore, extremely facilitated. The toner images 4 are formed on a carrier 2 by image forming means 1 to 6 using this toner, the image carrier 2 and a solvent 14 which can lower the viscosity of the toner. The viscosity of such images is lowered by the solvent 14, by which the transfer and the ordinary temp. fixing are simultaneously executed. The recorder (not shown) with which the good transfer efficiency and the bright images are obtd. with the simple device constitution and lower energy is obtd. in this way.

IPC: H01P11/00
Filed: 1986-05-19
Abstract: PURPOSE:To attain electrically stable line structure by forming a required conductor pattern to upper/lower faces of a printed circuit board so as to decrease warp or deformation of the board. CONSTITUTION:A ground conductor face only having the same width as a board width to be cut shown in single dot chains is left as a ground conductor 4 in the ground conductor face of a strip line on a rear side of the board 3 and the other conductor parts are removed by etching as the printed pattern circuit board. In applying reflow soldering to the rear side of the board, soldering is applied only to the part 4 where the conductor pattern reamins. The board with a carrier is cut off along a mark (single dot chains) on the board upper face to form a strip line where only the required part of board width is obtained. Since the ratio of areas of the upper/lower conductor parts of the board is decreased, the distortion of the board is made less. Further, the potential of the ground conductor face is made equal in terms of high frequencies.
