PURPOSE:To provide an image forming apparatus excellent in image quality and easy in manufacturing the same. CONSTITUTION:An aperture electrode body 1 of an image forming apparatus is constituted of a plurality of apertures 6, a substantially T-shaped control electrode portion provided at a part of an opening periphery of each aperture 6 and a conductor portion 5 extending from each control electrode portion to the downstream side in a direction in which toner 16 is fed, all of which being formed on an insulating sheet made of polyimide. According to these arrangements, a minimum distance between the control electrode portion and the conductor portion 5, which are adjacent to each other, can be sufficiently secured. Therefore, dielectric breakdown and the like are not caused, and a printing head having no trouble can be provided. |
