PURPOSE:To enable the same image to be formed simultaneously on plural sheets, by laminating a plurality of developing sheets each having a colored developing layer provided beneath a base to form a multiple developing sheet, adhering a toner to the multiple developing sheet, laying a paper beneath the multiple developing sheet, applying heat and pressure to the multiple developing sheet and the paper, and then releasing the bases and the paper. CONSTITUTION:Light reflected from a manuscript is directed to the surface of a photosensitive drum 2 by an optical system device 4 to form a latent image on the surface, and a toner C is adhered to the latent image by a developing device 6. A paper A is laid beneath developing sheets B, B', and the toner on the surface of the drum 2 is adhered to the developing sheet B by a transferring part 8. The developing sheets B, B' and the paper A are heated by a heater 13 and a fixing device 12. Colored developing layers B2, B2' are melted at parts corresponding to parts to which the toner C is adhered, and the melted layers are adhered respectively to a base sheet B1 and the paper A. Then, the paper A and the base sheets B1, B1' are released, whereby the colored developing layers B2, B2' are released respectively from the base sheets B1, B1', and the same image can be simultaneously formed on the base sheet B1' and on the paper A. |
