PURPOSE:To eliminate wrong recording and to form a high quality charge image, by supplying a plurality of recording voltages superposed to a recording electrode. CONSTITUTION:The title apparatus comprises high voltage switching circuits 151, 152,... for producing pulse voltages for deciding a recording pattern; circuits for forming primary voltage by integrating these pulse voltages; high voltage switching circuits 161, 162,... for producing pulse voltages for deciding recording positions; circuits for froming secondary recording voltages by differentiating these pulse voltages; and recording electrodes 181, 182,... for applying the primary and secondary voltages superposed. A charged image is formed on recording medium 7. |
