ABSTRACT:
In an electrophotographic image forming machine, an alternating current (AC) voltage is applied by an AC electric source with a constant frequency to a conductive wire and an electrode plate so that an electric field whose direction is inverted in synchronization with the frequency occurs. Consequently, the residual developer remaining on the front face of a photosensitive element vibrates and floats off the photosensitive element. A developer collecting roller is charged to the polarity electrically opposite to the polarity of the residual developer by application of a bias voltage from a direct current (DC) electric source. The residual developer separated from the front face of the photosensitive element is sucked and collected by the developer collecting roller with an electrostatic power developed between the developer collecting roller and the residual developer.
