Abstract

PURPOSE:To eliminate sticking of toner to an unnecessary part, by erasing an electric charge at an unnecessary part of a photoreceptor by the output of an optical signal generating part using a liquid crystal microshutter array in case of copying on narrow paper in the width to be copied to the maximum. CONSTITUTION:A copy process is exactly the same as that of conventional original moving types and a charge 9, a light source 22 for original, an optical system 10 for image formation, a quick imaging device 11 and a transferring device 12 are set around a photoreceptor 6. An optical signal generating part 18 has a liquid crystal microshutter array as a luminous intensity tone element and is added with a printing function. At the time of copying, a latent image of a part 5 as expressed by figure is erased by impinging a printing optical signal only on the part 5 of paper and a toner is not stuck entirely to an unncessary part.
