Abstract

An image forming apparatus uses an electrode member with apertures therein through which toner is passed according to an image. The electrode member has a lubricant layer contacting the surface of a toner carrier. The lubricant layer is made of molybdenum disulfide. Friction between the surface of the lubricant layer directly contacting the toner carrier and the toner particles carried thereon is so small that the adhesion of the toner particles is negligibly disturbed. Therefore, the switching control voltage for forming the image can be small.
