Compact Draw-off Type Instrument for Measuring Toner Charge
  DOI :  10.2352/ISSN.2169-4451.2002.18.1.art00049_2  Published OnlineJanuary 2002

We have developed a compact draw-off type instrument for measuring toner charge. The instrument can measure the charge to mass ratio (q/m) of both two-component and one-component developers. The instrument can also measure toner charge on a photoreceptor, or on several intermediate media or even on paper. The instrument is highly maneuverable due to the small size of its nozzle unit, thereby ensuring extremely versatile measurement capability. Toner particles are directly absorbed into a Faraday cage by means of a draw-off separation method, so that the measurements are highly accurate. We have found that accurate toner charge measurements could be obtained for two-component and one-component developers by using this instrument. This instrument should be useful for the further development of electrophotographic printing systems.
