Abstract

PURPOSE:To distinctly display a black part and a numeral, etc., which is void on the black part on copying paper with a simple constitution by providing a numeral light emitting element which moves near a photosensitive body drum so as to shade light in an exposure optical path. CONSTITUTION:When a user wants to copy numerals such as date, pages and registered number, etc., on the copying paper, the numeral light emitting element 7 is actuated by a control means 8. The numeral light emitting element 7 moves one range of outer peripheral surface of the photosensitive body drum 6 so as to shade the light for the image exposure (a) of an original 1 and makes static electricity residual on the photosensitive body drum 6. Then the numeral light emitting element 7 is made to emit the light by the control means 8 and the exposure of the numerals is executed on the part where the static electricity is residual. Thus, the black part and the numeral, etc., which is void on the black part can be distinctly copied on the copying paper.
