PURPOSE: To prevent contamination of a rear face electrode roller and forming of a toner image on a non-printing section of a paper, thereby realizing an image forming device capable of stably printing. CONSTITUTION: A rear face electrode roller 22 is connected to a rear face voltage applying circuit 24. When a paper 20 is not existing on an aperture 6 or a non-printing section of a paper 20 is existing there, an inhibition voltage of 1kV which inhibits the flying of a toner 16 is applied so that it is possible to prevent the toner 16 from flying toward the rear face electrode roller 22 even when the toner 16 erroneously goes outside of the aperture 6. |
