Abstract
A copying machine which produces one or more copied sheets by utilizing an electronic photographic method, wherein a coil shaped developing electrode is provided close to the traveling path of the photosensitive paper or the surface of the dram within the developing section of the device. Electric lines of force caused by an electrostatic latent image formed on the photosensitive paper or the dram are uniformly intensified as the paper or the dram pass near the developing electrode, whereby the edge development effects are suppressed and the contrast of the developing image is amplified in order to obtain a clean copy. A developer is replenished onto the photosensitive paper or the surface of the dram through clearances provided within the coil shaped developing electrode.
