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 has a control circuit. The control circuit initiates supplying transfer power to one or more first transfer rollers and to a second transfer roller when a first transfer operation is initiated by a first transfer roller positioned most upstream with respect to a direction in which an intermediate transfer belt travels. The control circuit stops supplying the transfer power to the one or more first transfer rollers and to the second transfer roller when a second transfer operation is completed by the second transfer roller. The transfer power supplied to the one or more first transfer rollers and to the second transfer roller, respectively, is free from fluctuation during a period from the initiation of the first transfer operation performed first to the completion of the second transfer operation.

摘要： A discharge unit is disposed downstream of a principal transport path of a compound machine, and a shifter function is provided in this discharge unit. By shifting the paper passage position relative to a photosensitive drum when printing the front side and the paper passage position relative to the photosensitive drum when printing the back side, the region in which the surface electric potential of the photosensitive drum increases is diminished, and the region in which photographic fog is generated is made smaller. Thus, when printing the second and subsequent sheets, even when a slight amount of displacement of the transport position of the recording paper occurs, it is possible to suppress that recording paper making contact in the photographic fog region on the photosensitive drum, and defective printing can be prevented.

摘要： A transfer device includes: a discharge type transfer element for transferring the developer to a sheet by discharging electric charge to a static latent image support through the sheet so as to form an image of an original thereon; and a transfer casing accommodating the transfer element, wherein the side on the sheet's entrance side is formed of an electrically insulating element, and is constructed such that the transfer element and transfer casing are arranged so as to be offset to the upstream side with respect to the rotational direction of the static latent image support, along the outer peripheral surface thereof and so that the upper end of the insulating element blocks up into the paper feed path, and the insulating element is adapted to be bent toward the sheet feed direction by virtue of an elastic member.
