ABSTRACT:
An electrophotographic apparatus capable of editing a copy picture image includes a document table for mounting a document thereon and a document irradiator for irradiating a surface of the document, and an optical system for focusing the reflected image from the surface of the document onto a photosensitive body so as to produce a latent image thereon. A photosensitive body irradiator is further provided for directly and selectively irradiating at least a part of the photosensitive body to erase a part of the latent image on the irradiated part of the photosensitive body. The resultant latent image is then developed in the usual fashion to form a visible image on a plain sheet. A position and function selector is provided separately from the document table and includes a tablet for first mounting the document thereon prior to the document being mounted on the document table and further includes a pen arranged such that a position on the tablet is detected by an access of the pen. The tablet is divided into a position selecting area and a function selecting area. Lastly, a controller is provided for controlling the document irradiator and the photosensitive body irradiator in accordance with signals from the position and function.
