689955, the control electrode disclosed in this specification includes two electrode layers with an insulating layer interposed between them.
Using this one with a Kll hole, this control voltage 11m
The purpose of this system is to control the passage of charged particles using K, and to obtain an image on a recording member provided on the side opposite to the charged particle supply source. However, in this method, it is difficult to make the aperture of the control electrode parallel to the recording member or the charged particle generation i1, which tends to cause unevenness in the image.The purpose of the present invention is to eliminate the drawbacks of the conventional example.
