PURPOSE:To make a device small in size, by constituting so taht a dielectric drum is used as a pressure fixing drum, too, and transfer and fixing can be executed directly to a medium from on the dielectric drum. CONSTITUTION:High voltage is applied to a dielectric drum 1 by the first high- voltage source 2, and on the other hand, high-voltage source 4, and in this state, a driving signal is applied to an aperture board 5 from a driving signal source 6. As a result, an electron emitted from the corona wire 3 is controlled so as to be made to pass through or to be obstructed, and on the dielectric drum, 1 an electrostatic latent image is formed. This electrostatic latent image is developed by a developing means 7, and after that, when a pressure fixing roller 10 is pressed against the dielectric drum 1, the image is transferred and fixed on a medium 9. |
