PURPOSE:To turn a transfer material upside down immediately after an image is transferred on one surface in a single feeding process and to transfer the image on the other surface. CONSTITUTION:This both-side image forming device is constituted so that a color toner image on the periphery formed by superimposing by one rotation of a photosensitive belt 10 and image exposing and developing actions taken in accordance with one rotation is transferred on the rear surface of a recording paper P fed by a feeding cassette 50 by a transfer unit 22A, the recording paper P is stuck/wound/held on a transfer holder 60 turned counterclockwise, by making an image surface outside and then, floated/held by the air current of an air duct 200 in such a manner that the part from the leading edge to the center is removed in the air duct 200 and a successively formed color toner image on the periphery of the photosensitive belt 10 is transferred on the surface of the recording paper P separated/carried from the transfer holder 60 whose rotation is changed clockwise by a transfer unit 22B, to transfer the images on both surfaces and simultaneously fix/record the images by the press- contacting and heating of the thermal rollers 81 and 82 of a fixing unit 80. |
