PURPOSE:To halve a time required for copying in case of generating many sheets of synthetic copies, by constituting the titled device so that a toner image which is formed on a film drum in the first process is transferred onto a transfer paper, but the toner image does not become an image of a copy but is left on a film. CONSTITUTION:The titled function consists of the first process in which the first original is exposed to a photosensitive drum 1 and its toner image is transferred to the outside peripheral surface of a film drum 11, and the second process in which while the photosensitive drum 1 rotates by a length portion of a copy, the second original is exposed to the photosensitive body and developed, its toner image is formed, also the photosensitive drum 1 is exposed through the toner image which is formed on the film drum 11 in the first process, a latent image against the first original is made, it is developed and a toner image is formed, and the toner image against the first original and the second original is transferred to the same transfer paper while the photosensitive drum 1 rotates by a one copy length portion. When generating plural sheets of synthetic copies, when generating the second sheet of copy and thereafter, the first process can be omitted. |
