PURPOSE:To obtain a distinct image by dividing an original image into a red component and a cyan component, carrying the first image information of the red component by a photosensitive drum, projecting the second image information of the cyan component of an ion current of negative of the opposite polarity, to said image information, and synthesizing a latent image. CONSTITUTION:An image of an original 44 is reflected by mirrors 62, 64, and made incident on a dichroic mirror 47. By its mirror 47, a cyan component is reflected, and a red component is made to transmit. Subsequently, the red component is advanced to a photosensitive drum 1 and the first image information is carried. Also, the reflected cyan component is advanced to a photosensitive screen drum 17 and the second image information is carried. Next, for instance, a photosensitive layer 56 of the photosensitive drum 1, and the screen drum 17 are electrified to positive and negative, respectively. In this state, a negative ion particle is projected from a charged particle source 19 of the screen drum 17, and it passes through the drum 17, negative image information reaches the photosensitive layer 56, and a latent image is synthesized. Accordingly, the latent image separated into a positive chromatic color level and a negative chromatic color level is formed on both sides of an achromatic color potential level, therefore, a distinct image can be obtained. |
