摘要： An armored unit includes a side cover and a guide member. When sheet jam operation is carried out, a fixing unit is pulled out with the armored unit, and then is pushed to the rear side. This operation unlocks the lock member provided in the guide member, and a shoulder screw moves in a guide hole. Thus, the fixing unit is moved from the pulled out position toward the rear side and toward the main body of image forming device to be shifted to a receding position. On this account, it is possible to provide an image forming device ensuring sufficient space for removing a jammed sheet by hand with a small opening space.

摘要： By application of a voltage from a power source, a transfer roller carries out both transfers of (A) a first transfer for transferring a toner image on a photoreceptor to an intermediate transfer medium and (B) a second transfer for transferring overlapped color toner image on the intermediate transfer medium at once onto a recording sheet. A transfer voltage in accordance with, for example, a sheet thickness, as detected by sheet type detection of a sheet type detecting section is applied to the transfer roller in each stage. When the sheet type detecting section detects that the recording sheet is longer than a periphery of a fixing belt, a heater lamp is turned on in advance at any instant between a time when the recording sheet is brought into contact with the fixing roller and a time when the fixing roller completes one rotation, taking into consideration a time required for conduction of heat from the heater lamp to the fixing belt. As a result, it is possible to reduce ozone generated and make the device compact, and desirable transfer characteristics in accordance with a sheet type are obtained, thus realizing uniform fixing of an unfixed toner image onto the recording sheet, from the front end to the rear end.

摘要： A displacement mechanism for a secondary transfer unit (40) includes a first eccentric cam (71), a second eccentric cam (72) and a shaft member (73). The first eccentric cam (71) and the second eccentric cam (72) are in contact with either edge portion of the secondary transfer unit (40) in width direction of a primary transfer belt (31), and rotate in phase with each other. The shaft member (73) supports the first eccentric cam (71) and the second eccentric cam (72). The first eccentric cam (71) is configured in such a manner that any radius in a peripheral portion (711) is of magnitude not less than a radius at a segment of the second eccentric cam (72) that is in phase with a segment of the peripheral portion (711). The second eccentric cam (72) is configured in such a manner that any radius in at least a segment of a peripheral portion (721) not including a press generating section (722) nor a separation generating section (723) is smaller than a radius at a segment of the first eccentric cam (71) that is in phase with the segment of the peripheral portion (721).
