Abstract (en)
A method and device for recycling a residual developing material on a photosensitive material after transfer step in an electrostatic copying apparatus wherein there is provided a blade member (12) capable of sliding to contact with and separating from the photosensitive material (2) upstream with respect to a corona charger (4) for charging the photosensitive material (2) before exposuring step along the moving direction of the photosensitive material (2). The blade member (12) slides to contact with the photosensitive material (2) during the time when a latent image is formed onto the photosensitive material (2) in a developing step, and separates from the photosensitive material (2) during the time when the latent image is not formed in the copying operation. The developing material accumulated on the photosensitive material (2) by means of the blade member (12) in the exposuring step travels to be stored at a developing device (6) according to the movement of the photosensitive material (2).
