ABSTRACT:
In a transfer type electrophotographic copying machine, the amount of supplied toner is controlled in accordancw with the voltage developed by the reflection of light from an indexing image developed on the photosensitive member before or behind the transferred developed image; the same reflected light also detects the presence of an unseparated transfer sheet to stop the machine.
