Abstract

PURPOSE:To perform partial copying easily by modulating the laser beam scanning a uniformly charged photosensitive drum surface according to printing information, or displaying the printing information on a cathode ray display tube opposing to the photosensitive drum. CONSTITUTION:A photosensitive drum 5 is so designed that when it rotates in the arrow A direction the surface of the drum 5 passing a charger 9 is uniformly charged. A laser exposure part 7 is so constituted as to irradiate the laser beam 8 modulated by the modulating signal corresponding to the printing information from a printing control part 6 to the above-mentioned uniformly charged photosensitive drum. At the time of projecting an original 2 onto the drum 5 in this case, an original cover 3 is disposed in contact with the back surface of the original 2 as shown in the figure. Thereby, partial copying is accomplished easily without the need for changing the original cover and the like in spite of a change in the size of an original for copying or the like.
