ABSTRACT:
An electrophotographic copying machine includes a device for removing charges of portions of a latent image bearing element which are unnecessary for forming a latent image. The device includes a light source, the latent image bearing element, and a light shade plate which is positioned between the light source and the latent image bearing element. The light source is positioned at the focus point of a fresnel lens. The device can be applied to a type of electrophotographic copying machine having a three-layered latent image bearing element.
