    摘要: An intermediate transfer type image forming apparatus is provided, in which a secondary transfer unit includes a secondary transfer member having a contact transfer member disposed in contact with at least the surface of an intermediate transfer medium, a bias applying unit for applying a transfer bias to transfer a toner image on the intermediate transfer medium through the secondary transfer member to a transfer medium and an inverse transfer bias having the opposite polarity to the transfer bias, and a bias switching unit for switching the applied bias of the bias applying unit so that the transfer bias is applied to an image transfer area on the intermediate transfer medium and the inverse transfer bias is applied to an image non-transfer area on the intermediate transfer medium. The apparatus is also equipped with a disturbing member for disturbing (scraping out, sweeping off or the like) toner adhering to the contact transfer member.

    摘要: An apparatus and techniques for reducing the electrostatic sticking of a transfer member to the image carrying body of an image forming apparatus. The visible image on the image carrying body is formed by charged participles. A collective transfer unit collectively transfers the visible image from the image carrying body to a transfer member. A transfer member judging unit judges whether a transfer member exists downstream of and in the vicinity of a transfer position of the collective transfer unit. A pre-stop processing unit for preventing, if the transfer member presence judging unit judges that a transfer monitor exists when the stopping unit stops the device, the transfer member from electrostatically sticking to the image carrying body.

    摘要: There is described an image forming apparatus, wherein a visible image retained on an intermediate transfer belt is collectively transferred to recording material by means of a collective transfer device including a transfer roller and a back-up roller. The recording material that has passed through a transfer nipping region is guided by means of a recording material guide member. In such an image forming apparatus, the intermediate transfer belt is set at an angle of 50.degree. or less relative to the reference line passing through the exit of the transfer nipping region between the transfer roller and the back-up roller among normals orthogonal to a line passing through the center shafts of the transfer roller and the back-up roller, in the area downstream from the transfer nipping region, and the recording material guide member is provided downward at an angle of 5.degree. to 20.degree. relative to the reference line L.
