PURPOSE:To make it possible to easily form a colored image by simple strucure, by providing a dichroic filter and a mirror on the regular related position, and forming a latent image of complementary color relation and reflected image relation on the photosensitive body and the charged particle flow control screen, respectively. CONSTITUTION:The filter 14 and the mirrors 15, 16 are provided so that the light passage length of the first reflection which reaches the photosensitive drum 2 through the mirror 15 from the dichroic filter 14 can be equal to the light passage length of the twice reflection to the charged particle control screen 3 by being reflected by the filter 14 and subsequently by the mirror 16. In this regard, since the rotary movement of the drum 2 synchronizes with the linear movement of the screen 3, a latent image of complementary color relation and reflected image relation is formed on the photosensitive body 2 and the screen 3, respectively. Accordingly at the time of the first rotation of the photosensitive body 2, in case a colored filter 17 such as red, etc. is used instead of the filter 14, an image of the original black image part, etc. is formed on the photosensitive body 2. At the time of the next rotation, a latent image of the red image part which is formed on the screen 3 is transferred to the photosensitive body, and at the time of the third rotation, a colored image is formed on the trasfer paper. As mentioned above, the operation can be performed easily by a few processes and simple structure. |
