摘要： In this toner concentration sensor, as the magnetic permeability of a two-component developer 3 containing toner and carrier in a two-component developing unit 1 has changed with changing TC ratio of the two-component developer, the oscillation frequency of a first oscillation circuit 20 having a detection coil 5 changes, on the other hand the oscillation frequency of a second oscillation circuit 30 having a reference coil 6 does not change. While, changes in temperature conditions cause the oscillation frequency of the second oscillation circuit to change in the same way as the oscillation frequency of the first oscillation circuit. Therefore, utilizing a difference between the oscillation frequencies of the first and second oscillation circuits makes it possible to cancel out changes in the temperature conditions so that a value corresponding to only the magnetic permeability of the two-component developer can be obtained. Thus, detection errors of toner concentration due to temperature changes can be reliably prevented.
摘要翻译： 在该调色剂浓度传感器中，随着双组分显影单元1中含有调色剂和载体的双组分显影剂3的磁导率随着双组分显影剂的TC比的变化而改变，第一振荡电路的振荡频率 具有检测线圈5的20变化，另一方面，具有基准线圈6的第二振荡电路30的振荡频率不变化。 而温度条件的变化导致第二振荡电路的振荡频率以与第一振荡电路的振荡频率相同的方式变化。 因此，利用第一和第二振荡电路的振荡频率之间的差异，可以抵消温度条件的变化，从而可以获得仅对应于双组分显影剂的磁导率的值。 因此，可以可靠地防止由于温度变化引起的调色剂浓度的检测误差。
