ABSTRACT:
An electrophotographic copier comprises an optical system for projecting an original image onto a photoreceptor to form an electrostatic latent image thereon, and a movable LED array for forming an electrostatic latent image corresponding to additional information on the photoreceptor. A seal is applied to a bottom face of an original-supporting glass table for retaining electric charge of a selected region of the photoreceptor by partially intercepting the original image projected by the optical system. The LED array is switchable between a mode for recording the additional information on the selected region of the photoreceptor, and a mode for erasing the charge of the selected region.
