PURPOSE:To make feeding of a toner to an aperture smooth and to make recording characteristics such as resolution good by using a recording electrode the surface of which facing to the charged particle feeding side in the neighborhood of the aperture is made rough and performing recording by direct controlling. CONSTITUTION:A toner is rotatably moved by being pinched between a base material 31 of an aperture electrode and a carrying roller 23. In this case, as the surface of the base material 31 is formed into a rough face and in addition, the surface roughness is smaller than the particle diameter of the toner, the toner 27 is well bited on the surface and the behavior is extremely smoothed. As the result, the amt. and characteristics of the toner fed to the aperture is homogenized. In a recording electrode 30, a signal from a data circuit is transmitted to a driving circuit through a conductive part and in practical, 0 volt and 60 volt are selectively applied on an aperture electrode 33. In this instance, an electric field is generated between the earthed carrying roller 23 and the aperture electrode 33 and the toner 27 pinched between the recording electrode 30 and the carrying roller 23 is energized by an electrostatic force and control of recording can be performed. |
