    • A device is provided which is capable of removing the charge of a recording medium, even a low charge. The recording medium has an electrically-conductive layer and dielectric layers, and is used for forming a toner image by an image forming apparatus. The device includes a first charge-removing electrode in contact with the electrically-conductive layer of the recording medium and a second charge-removing electrode which is in contact with the dielectric layer of the recording medium and is positioned on a side of the recording medium which is opposite to the side of the first charge-removing electrode. A voltage with the same polarity as that remaining on the surface of the dielectric layer of the recording medium is applied to the first charge-removing electrode, and a voltage with a polarity opposite to that remaining on the surface of the dielectric layer is applied to the second charge-removing electrode.
    • 提供了能够去除记录介质的电荷的装置,即使是低电荷。 记录介质具有导电层和电介质层,并且用于通过图像形成装置形成调色剂图像。 该装置包括与记录介质的导电层接触的第一电荷去除电极和与记录介质的电介质层接触并位于记录介质侧的第二电荷去除电极 其与第一电荷除去电极的侧面相反。 向第一电荷去除电极施加与记录介质的介质层表面上剩余的电极相同极性的电压,并将与电介质层表面上残留的极性相反的电压施加到 第二电荷去除电极。
