Abstract

PURPOSE:To extend a printing function and to attain the reduction in a printing cost and the simplification of maintenance by obtaining a positive image from both negative and positive image information. CONSTITUTION:An exposure unit 1 is constituted of a light source 5, a lens 6 and a mirror 8, etc., and a negative or positive slide film 4 can be interchangeably loaded in the optical system thereof. And in case of obtaining the positive image from the negative image information, light is projected on the surface of a photosensitive body 9 to make electrifying substance 17 adhere based on the negative image information and then the electrifying substance 17 on a light non-projecting area on the surface of the photosensitive body 9 is removed to obtain the positive image. Meanwhile, in case of obtaining the positive image from the positive image information, the positive image can be also obtained by removing the electrifying substance 17 on the light projecting area on the surface of the photosensitive body 9. Since the positive image can be obtained from both negative and positive image information, multifunction can be attained and the operation and the maintenance of a device can be facilitated, then the image can be formed at low cost.
