ABSTRACT:
An image forming device of the type using an aperture electrode assembly in which toner passage through apertures formed is controlled in accordance with a drive signal and the toner particles selectively pass through the apertures to form an image on a recording medium. The aperture electrode assembly includes an electrical insulation sheet and a plurality of control electrodes formed thereon. Wrinkles are prevented from occurring in the insulation sheet when the electrode assembly is secured to a frame or the wrinkles, even if generated resulting from mounting of driver IC chips on the insulation sheet, do not spread to the vicinity of the apertures.
