    • Developer density in an electrophotographic system is measured. The developer includes toner particles and magnetic carrier particles. First and second mutually-insulated electrodes define a working volume between them through which developer passes without contacting the first electrode. An AC voltage or current source is connected to the electrodes. An inductor is connected in series with a voltage source, or an inductor is provided in parallel with a current source. The voltage or current is applied and corresponding current or voltage across the electrodes is measured. The density of the developer in the working volume is automatically determined using a processor responsive to the measured current or voltage and the applied bias.
    • 测量电子照相系统中的显影剂密度。 显影剂包括调色剂颗粒和磁性载体颗粒。 第一和第二相互绝缘的电极限定了它们之间的工作体积,显影剂通过该工作体积而不接触第一电极。 AC电压或电流源连接到电极。 电感器与电压源串联连接,或者电感器与电流源并联。 施加电压或电流,并测量电极两端的对应电流或电压。 使用响应于测量的电流或电压以及所施加的偏压的处理器来自动确定显影剂在工作体积中的密度。
