Abstract
An electrophotographic copying apparatus which is so arranged that control of its copying functions has been simplified for efficient copying operation by reducing the number of signals for controlling the copying functions, whereby respective devices for corona charging, transferring, separating and developing may be controlled by a single signal, while the number of high voltage sources for supplying power to the corona charger, transfer charger, separating charger and developing sleeve, etc. has also been reduced for simplification.
