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.
摘要翻译：传送装置具有控制电路。当通过相对于中间转印带行进的方向位于最上游的第一转印辊开始第一转印操作时，控制电路开始向一个或多个第一转印辊和第二转印辊提供转印力。当通过第二转印辊完成第二转印操作时，控制电路停止向一个或多个第一转印辊和第二转印辊供应转印电力。在从首先执行的第一传送操作开始到完成第二传送操作的时间段期间，提供给一个或多个第一传送辊和第二传送辊的传送功率分别没有波动。

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 primary transfer rollers supported so as to be upwardly and downwardly movable within a path of movement and opposed to respective of photosensitive drums across a portion of an intermediate transfer belt. There are also provided a slide member for full-color image formation and a slide member for monochromatic image formation, which are capable of reciprocation in a horizontal direction. The transfer device includes roller lifting means each L-shaped and each having one end supporting an associated one of the transfer rollers for rotation and another end engaging an associated one of the slide members, and first and second coaxial rotating cams. The transfer device is capable of switching between three paths of movement of the intermediate transfer belt selectively by the first and second rotating cams rotating together.

摘要： An image forming apparatus includes a pair of optical sensing devices for monochrome image forming and full-color image forming which are disposed at the rear of the image forming apparatus and a pair of generally L-shaped light shielding members for monochrome image forming and full-color image forming which are mounted swingably on a rear side of an image transfer unit with one end of each light shielding member attached to one of two sliding members. When each of the sliding members moves back and forth, the light shielding member for monochrome image forming or full-color image forming, whichever applicable, swings and the relevant optical sensing device detects the other end of the light shielding member.
