<p>Toners 17 supplied from a feed roller 2 of a printing unit 1 and projected through electric field control by a printing control electrodes 20 are accelerated by a voltage applied to a transfer belt 7 from an acceleration voltage source 9. The toners 17 deposited onto the transfer belt 7 by the printing unit 1 moving in the direction vertical to the paper surface are transferred onto recording paper 13 by a fixing device 16 and fixed on the recording paper 13 by heating. Since a toner image is formed on the transfer belt 7, a stable image is formed and it is not easily influenced by the thickness of the recording paper 13 or environment. A plurality of developing agent units 101, 102, 103, and 104 different color toners are used for color printing. <IMAGE></p> |
