Abstract: PROBLEM TO BE SOLVED: To obtain a practically sufficient density contrast with a practically low driving voltage at the formation of images, by using a toner which has a smaller primary particle size than a minimum inner diameter at an opening hole part and forms an aggregate larger than the inner diameter. SOLUTION: When a toner 16 which is hard to pass a mesh of a size close to a minor axis of an aperture 6 is carried on a carrier roller 14 immediately after passing a toner reservoir 21, a feed roller 12 and a layer regulation blade 18, the toner forms an aggregate slightly larger than the minor axis of the aperture 6. The aggregate receives a mechanical force at a contact part between the carrier roller 14 and an aperture electrode body 1, and therefore is separated. Moreover, because of an action of an electric field when the apparatus is turned on, a sufficient amount of the toner 16 to obtain a practical reflection density at the on time passes the aperture 6 and flies. At an off time, the toner aggregate is hard to pass the aperture 6 and to fog even when an impression voltage is low.
