在电子照相的定影器处理中，缺陷可能由称为静电偏移的现象引起，其中图像拖尾是由定影器构件旋转一圈之后来自定影器构件的调色剂粘附到纸上引起的。该调色剂通过静电力从纸转移到定影器构件。静电偏移的发生取决于定影器构件的电阻率和定影器输送辊的电势。在这项研究中，我们计算了定影器夹区域的电场，通过结构计算确定了定影器夹的形状，从而研究了静电偏移发生的物理机制。我们还发现静电偏移的发生可以通过定影器辊隙区域的电场强度和调色剂的电荷分布来预测。
In the fuser process of electro-photography, defects may be caused by a phenomenon called electrostatic offset, in which image smear is caused by toner from the fuser member adhering to the paper after one rotation of the fuser member. This toner is transferred from the paper to the fuser member by electrostatic force. The occurrence of electrostatic offset depends on the electrical resistivity of the fuser member and electric potential of the fuser delivery roller. In this study, we calculated the electric field of the fuser nip region, determined the shape of the fuser nip by structural calculation, and thus examined the physical mechanisms by which the electrostatic offset occurs. We also found that the occurrence of electrostatic offset can be predicted by the electric field strength of the fuser nip region and the electric charge distribution of toner.
