PURPOSE:To eliminate unevenness in the density of setting by correcting the difference in conduction quantity due to different conduction paths. CONSTITUTION:There provided are a plurality of record electrodes 101, a power source 102 for imparting potential difference to each of the electrodes 101 and a common electrode (not shown), (n) number of resistances R1-Rn disposed between each electrode and the power source 102, and an actuation control circuit 103 for actuation control of each record electrode by inputting specified image signals, wherein resistance values of respective resistances R1-Rn are set so as to satisfy the relationship of R1<R2<R3<R4<...<Rn/2>...>Rn-2>Rn-1>Rn. By providing this relationship, the differences in conduction quantity due to different conduction paths can be canceled. |
