An image forming apparatus uses an electrode member with apertures therein through which toner is passed according to image data to form an image on a supporter. The electrode member has an insulative inorganic substance formed thereon to protect a surface of the electrode member from wear. Thus, the supply of toner through the apertures in the electrode is stable. Further, since the protection layer of inorganic substance is arranged on the toner carrying roller side of the aperture electrode member, the image forming apparatus has an excellent image forming property.
