PURPOSE:To complete a two color copy within one operation of a photosensitive body, and also to obtain a free mixing color tone by constituting so that the first electrostatic charger, the second charger, an optical image irradiation, also, the first developing machine, the thrid charger, a light source and the second developing machine are placed successively in the circumference of a polarized photosensitive body. CONSTITUTION:As for a photosensitive body 4, a transparent thin layer 3 having a high insulating property, a polarized photosensitive layer 1 and an electrode layer 2 are laminated successively on its surface. Also, on its circumference, the first charger 5, the second charger 6 which has the polarity opposite to said charger 5 and is capable of irradiating simultaneously the first reflected light image 7 which lackes charging and some color, an irradiation 8 for projecting the second reflected light image of said some color, the first developing machine 9 for visualizing a bright part of the reflected light image of this irradiation 8, the third charger 10 for converting the surface of the photosensitive body 4 to the lower potential than the potential provided by the second charger 7 at the opposite polarity side, a light source 11 for irradiating the whole surface of the photosensitive body 4, and a developing machine 12 for visualizing an optical image which is made incident by the irradiation 8 are placed successively. |
