PURPOSE: To prevent the indistinctness of an image projected by an OHP caused by the curling of a transparent film after a toner image is formed. CONSTITUTION: A controller 10 forms an erecting latent image on the surface of a charged photoreceptor drum 1 with an exposure means 3, when a paper kind sensor 9 detects the fact that a recording material P supplied to the drum 1 from a paper feeding cassette 7 is of the transparent film such as an OHP sheet. Toner is stuck to the erecting electrostatic latent image by a developing unit 4, to turn this latent image into an erecting toner image. When this toner image is transferred to the surface of the transparent film by a transfer roller 5, the toner image becomes a mirror image. After this mirror image is fixed, the transparent film is curled having the mirror image side inside. At the time of projecting by the OHP, the transparent film is placed so that the mirror image side faces down, on a projecting plate. Thus, the curling of the transparent film is reduced by its own weight and the sharpness of the projected image magnified as an erecting image is increased. |
