    摘要： A secondary transfer unit stretches a transfer belt in an endless form over a driving roller, a driven roller, a transfer roller, an auxiliary roller, and a support roller therebetween. The transfer belt moves, by rotation of the driving roller, along a circulation path which passes through a transfer position. The transfer roller and the auxiliary roller press the transfer belt from the inner peripheral surface of the transfer belt toward an intermediate transfer belt in the transfer position. The transfer belt has an outer peripheral surface thereof which is pressed against the intermediate transfer belt and is roughened so that the surface roughness of the outer peripheral surface becomes 6 μm to 10 μm.

    摘要： A transfer device includes a transfer belt, a transfer roller and a tension roller over which the transfer belt is passed in a tensioned condition and which is made to be in an electrically floated state; it also includes a guide member that is installed in the vicinity of the tension roller. A control section, in transfer processing, controls a first switch so that the guide member is in a grounded state while controlling a second switch so that an electric current being caused to flow to the transfer roller becomes a first electric current; and in cleaning processing, controls the first switch so that the guide member is in an electrically floated state while controlling the second switch so that an electric current being caused to flow to the transfer roller becomes a second electric current.

    摘要： A transfer device is provided including an intermediate transfer belt and transfer rollers associated with respective of photosensitive drums. Each of the transfer rollers and the intermediate transfer belt define therebetween a contact range of which center lies downstream of the center of a contact range (transfer nip region) defined between the associated photosensitive drum and the endless belt in the direction of movement of the endless belt. The transfer roller deforms the path of movement of the intermediate transfer belt by contacting the intermediate transfer belt, and the resulting deformation causes the intermediate transfer belt to contact the periphery of the photosensitive drum over a predetermined range.

    摘要： A transfer device has a plurality of first transfer rollers provided, one in each of a plurality of first transfer regions. The first transfer rollers are arranged downstream of respective image carriers in a traveling direction of an intermediate transfer belt, so as to be out of contact with the image carriers through the belt. In the first transfer region that is located most upstream in the traveling direction, there is a pressure member provided upstream of the image carrier in the traveling direction for pressing the intermediate transfer belt against the image carrier.

    摘要： A transfer device includes a plurality of primary transfer rollers, a second link member and a regulatory member. The regulatory member restrains the second link member from moving further than a predetermined position toward the second direction. The second link member causes the primary transfer rollers to be displaced as it moves. The second link member is split into a plurality of link arms of which overall length is variable within a predetermined range; and its joint portion includes an elastic member urging the plurality of link arms toward a direction to which the overall length gets longer in a state where the second link member is most separate from a cam shaft, and a first locking section and a second locking section engaging the plurality of link arms with one another for the overall length not to get longer beyond a maximum value.
