Abstract
A method and apparatus utilizing a controller having a plurality of openings or slit-like openings to control the passage of charged particles and to record a visible image by the charged particles directly on an image receiving member. The present invention is an improved device for supplying the charged particles to a control electrode and has made high-speed and stable recording possible. The improvement lies in that the charged particles are supported on a supporting member and an alternating electric field is applied between the supporting member and the control electrode. Thus, it has become possible to sufficiently supply the charged particles to the control electrode without scattering them.
