PROBLEM TO BE SOLVED: To realize the high speed recording by generating static for scattering toner separated from a toner carrier toward a recording component and forming continuously the electric field not scattering new toner from the toner carrier in the case of not applying the voltage for forming an energy to a control electrode. SOLUTION: The scattering of toner is controlled by a control electrode 5 by providing the voltage to the toner on a toner carrier 6a, and the voltage for forming an image which can generate the scattering of the toner to an image electrode 51 is applied in compliance with image signals, and static is generated on a conductive toner 91 layer surface by the voltage. After the toner is separated from a toner layer and the scattering is started, however, the toner is scattered as it is continuously even in the case of lowering the voltage and the electric field is weakened. In that case, the image electrode 51 is provided with the voltage of 180V at the time of forming the image and the voltage of 120V at the time of not forming the image. Therefore, it is not necessary to wait for the changeover of the image electrode until the toner is passed through a hole 54 of the control electrode 5 and the high speed can be realized. |
