Abstract
A copying machine capable of copying originals on the front and back faces of each copy medium comprises a photosensitive medium, a charger for electrostatically charging the photosensitive medium, an optical system for projecting an original image upon the photosensitive medium to form an electrostatic latent image thereof, a developing device for developing the latent image into a transferrable image, a transfer device for transferring the transferrable image onto copy mediums, a first feeder for feeding copy mediums for the front-face copying, a reversing mechanism for reversing the copy mediums fed by the first feeder after the image transfer, and a second feeder for temporally stopping the copy mediums, after reversal, on their way to the transfer device and for feeding the reversed copy mediums to the transfer device for back-face copying.
