摘要： Developer flow rate over a rotatable development member (7,10) in an electrophotographic system is measured. An electrode (4,15) and the development member define a capacitive working volume (4,20) between them through which developer moves. A voltage source electrically connected to the electrode and the development member selectively applies an AC bias across the working volume, and a meter (7,40) measures the currents across the working volume while the bias is applied. A controller causes the development member to stop supplying toner to the photoreceptor, and to rotate. While the development member is rotating, the controller records the current measured by the meter. Developer flow rate is computed using the measured current. The developer flow rate can be adjusted in response to the computed flow rate.

摘要： Developer toner concentration in an electrophotographic system is measured. Two sensors (1120, 1130), one before and one after the toning zone (1110) in the direction of rotation of the development member (1171), each include respective electrodes that form a respective capacitance between the respective electrode and the development member. A voltage source (430) selectively applies respective AC biases across the sensors and the respective currents across the sensors are measured. A controller (1170) causes an electrostatic latent image to be produced on the photoreceptor (206) and causes the development member to rotate and the photoreceptor to move. While the development member is rotating, the processor receives the measured currents and computes toner concentration using the respective received currents and the pixel data. The developer flow rate can be adjusted, or toner added to the developer, in response to the determined toner concentration.

摘要： Developer density is measured in an electrophotographic system (100). First an second electrodes (410, 415) are disposed to define a working volume (420) between them through which developer passes without contacting the first electrode (415), wherein the electrodes are electrically insulated from each other by the working volume. One terminal of an AC voltage (current) source (430) having a selected frequency is connected to one of the electrodes. An inductor (919) is connected in series (parallel) with the voltage source, so that the source provides the AC bias (current) across the electrodes through (across) the inductor. The AC is applied and the current (voltage) across the electrodes is measured. The density of the developer in the working volume is automatically determined using a processor (450) responsive to the measured current (voltage) and the applied bias (current).

摘要： An apparatus for measuring developer density in an electrophotographic system (100). A first electrode (415) and a second electrode (410) are disposed to define a working volume (420) between them through which developer (514) moves without contacting the first electrode (415), wherein the electrodes are electrically insulated from each other by the working volume. A voltage source (430) selectively applies an AC bias across the electrodes. A measuring device (A) measures the current across the electrodes while the bias is applied. A processor (450) is adapted to automatically determine the density of the developer in the working volume based on the measured current and the applied bias.
