Abstract

PURPOSE:To record easily different optical information, by forming latent images of charging potential of different polarities on the same photoreceptor in accordance with different optical information. CONSTITUTION:Optical information of the first color from an original 23 is applied to a photoreceptor 9, and the photoreceptor is charged uniformly with a positive polarity by the first corona discharger 10, and a latent image having positive polarity is formed on the photoreceptor 9. All of the surface of the photoreceptor 9 is exposed by an overall exposure lamp 121, and a latent image having a negative polarity of the second color from an original 28 is formed on the photoreceptor 9 similarly through the second corona discharger 11 for AC discharge. The photoreceptor 9 is processed in an overall exposure lamp 122, developing devices 14 and 15 using toners different in polarity and color, etc., and thus, different optical information of two colors or the like are recorded easily with a small-sized constitution.
