Abstract
In this report the authors describe the investigatreory sults on the response characteristics of electrometers for electrophotography.
The test was carried out measuring rectangular wave voltages, and electrophotographic paper potentials, showing that the error due to delayed response cannot be neglected for the rotating vane type electrometer under some conditions.
Turthermore the photo-current on a light sensitive layer was measured approximately by differentiating the output of the standard electrometer
