Abstract
PURPOSE:To obtain an appropriate color balanced image by enabling the checking of electric potential of the surface. CONSTITUTION:A computer 109 supplies digital signals to an I/O driver 161 through a bus line 117. Figure scanning of a display device 163 is performed by this I/O driver 161 and a display signal 165 from the computer 109 is input to a BCD-7 segment driver 167. Then, the electric potential of the surface of a sensitive drum is displayed on the display device 163 by this output signal 169. A diode switching board 171 is scanning-controlled through the I/O driver 161 and set target value is respectively selected in order on a switching board 115. The set and selected voltage signal of the target value is sent to the computer 109 and is operated in accordance with the respective control formulas to converging to the respective target values.
