Abstract (en)
[origin: EP1253481A2] Image forming device comprising an image forming element (10) moving past an image forming station (12) in which toner (38) is deposited on the surface of the image forming element, said image forming element having at least one electrode (22, 24) extending over a predetermined surface area (20) of the image forming element, characterized by a impedance/capacitance measuring circuit (42) measuring the amount of toner deposited on said predetermined surface area (20) on the basis of a resulting change in the impedance/capacitance of the electrode (22, 24).
