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： When handle region(s) of disengaging lever(s) is/are pulled in direction(s) tending to cause disengagement of engagement between access-controlling body or bodies and main body housing(s), respective action edge(s) of rotating region(s) may rotate about shaft(s) in direction(s) tending to cause disengagement of engagement. Upon rotating in direction(s) tending to cause disengagement of engagement, respective action edge(s) of rotating region(s) may press on and impel support plate(s) of main body housing(s). In accompaniment thereto, disengaging lever(s) may move upward, and respective downwardly directed engagement projection(s) of access-controlling body or bodies may be lifted up and extricated from respective upwardly directed engagement projection(s) of main body housing(s). Moreover, when handle region(s) of disengaging lever(s) is/are pulled, respective sliding frame(s) of access-controlling body or bodies may move along respective guide rail(s) of main body housing(s) and toward exterior(s) of main body housing(s), greatly opening up access at opening(s) of main body housing(s).

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 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 rotation speed of a heating roller 39a and a pressure roller 39b is variably controlled by a CPU 542 based on a sheet size to be printed, a direction the sheet is to be passed, and a number of sheets to be printed. Specifically, variable control of the rotation speeds of the heating roller 39a and the pressure roller 39b by the CPU 542 is based on an occurrence of a pass-through area 39b1 and a non-pass-though area 39b2 by a sheet of recording paper with respect to a roller lengthwise direction (axial direction) of a position at which the sheet of recording paper passes between the heating roller 39a and the pressure roller 39b, and controlled based on a thermal expansion coefficient of a roller diameter of the non-pass-though area 39b2 of the pressure roller 39b.
