Abstract

PURPOSE:To obtain an image having various densities which are continuously gradational at the same hue by repeating plural times of electrification and exposing and electrifying again uniformly a photosensitive body prior to development. CONSTITUTION:A photosensitive body 1 which is uniformly electrified by the 1st corona electrifier 2 is exposed imagewise by the 1st exposing light source 3 having increased exposure, by which an electrostatic latent image is formed and further the photosensitive surface thereof is uniformly electrified by the 2nd constant current type corona electrifier 4. The uniformly electrified photosensitive surface is exposed with the same image by the 2nd exposing light source 5 in succession to the above-mentioned electrification and is further uniformly electrified by the 3rd constant current type electrifier 6. The image having excellent various densities which are continuously gradational is thus obtd. at the same hue.
