<p>PROBLEM TO BE SOLVED: To improve the responsiveness of a toner flow when an aperture electrode body is kept on or off, uniformly and quickly attain saturation electrification, and form an image having sufficient density contrast with a low driving voltage for driving the aperture electrode body. SOLUTION: This image forming device is provided with a toner feeding device 10 and an aperture electrode body 1 having multiple apertures 6, the aperture transit of the electrified toner 16 fed from the toner feeding device 10 via the aperture electrode body 1 is controlled, and an image is formed on the printing paper arranged near the aperture electrode body 1 on the opposite side to the toner feeding device 10. The toner 16 is mixed with the negative electrification toner and the positive electrification toner preferably at the prescribed range 95:5-80:20 between the negative electrification toner and the positive electrification toner.</p> |
