PURPOSE:To improve picture density without increasing a recording voltage by increasing the carrying speed of a toner carrier for carrying a toner layer larger than the carrying speed of a recording medium. CONSTITUTION:When the toner layer 18 carried by the toner carrier reaches the position of a stylus 46, i.e. the position of a recording electrode, the electric field strength between the stylus 46 and an opposite roller 42 is changed by the recording voltage 44 to be changed in accordance with recording information, but a part of the toner layer 18 positioned on the recording electrode is repulsed by electrostatic force having the same polarity as the charging polarity of the toner and adhered to recording paper 40 and the residual toner is stagnated on the toner carrier 10. When it is defined that the carrying speed of the toner carrier 10 is Vs and the carrying speed of the transfer paper 40 is Vp, a toner image having high picture density can be obtained by forming Vs>Vp. |
