Abstract: PURPOSE:To eliminate the density difference among images formed successively, by preexposing a photoreceptor surface before formation of a static latent image, and controlling that light intensity enough to erase its hysteresis and so as to render the contrast of the latent image constant. CONSTITUTION:Light source 11 such as tungsten lamp as preexposing means, destaticizer 12 for erasing residual charge, primary corona discharger 13 for forming a latent image, etc. on photosensitive drum 1 are arranged above the circumference of drum 1.
