Abstract
An edge electrode includes a plurality of control electrodes formed on an insulation sheet. The insulation sheet 2 is a 25 .mu.m thick layer of polymide. A recording surface is provided at a thickness side of the insulation sheet. The edge electrode is disposed so that the recording surface is adjacent to toner borne on a toner-bearing roller. A recording edge is provided as a narrow surface of the insulation sheet bordering the recording surface and confronting a back-electrode roller. The control electrodes are formed on the recording edge confronting a recording medium. Each control electrode is formed to about 1 .mu.m thick on the recording edge. The control electrodes are formed at an interval of about 125 .mu.m. The dimension of the control electrodes in the direction following the recording edge is about 100 .mu.m.
