PURPOSE:To obtain an image of good quality by making the transferring member of one side into a roller. CONSTITUTION:Onto a photosensitive body 1, conductive transfer roller 6 abuts, a transfer bias is impressed, and for a transfer material from a carrying route 51, a toner image is transferred by a bias in an abutting nip part between the photosensitive body 1 and roller 6. An unnecessary charge is discharged by a discharging needle 6a, the transfer material is separated from the photosen sitive body 1, and it is fed to the transfer part of a second image forming means F2. For the transfer material to carry the toner image on a first surface by a first image forming means F1, the toner image is transferred on the second surface by the means F2, the unnecessary charge is discharged by a discharging needle 9a, the transfer material is separated from a photosensitive body 1', and the toner image is completely fixed by a fixing device 10. Since the means F1 is due to the transfer roller, the holding and carrying of the transfer material are sure, the transfer material can be correctly carried to the transfer part of the means F2, and thereby, the image of good quality can be obtained. |
