Abstract
This invention relates to means of separating a copying paper from a sensitive body in an electronic copying machine, said means making it easy and sure to separate the former from the latter by controlling variably a voltage for removing electric charges by detecting variations of a differential current between the current flowing to an electrode of a charged device for copying, i.e. quantity of electric charges given to the copying paper and the current flowing to a shield case of the charged device.
