摘要： An image forming apparatus includes at least one image carrier and a recording medium conveyor forming a transfer nip therebetween, a conveyance member disposed closest to the transfer nip on an upstream side of the transfer nip to convey the recording medium to the transfer nip, and a conveyance control mechanism to deactivate the conveyance member to stop providing a conveyance force to the recording medium after the leading edge of the recording medium has entered the transfer nip and before the trailing edge of the recording medium passes a point of force application and remaining in the inactive state until the recording medium passes the point of force application. The conveyance force remains unapplied to the recording medium from when the conveyance control mechanism deactivates the conveyance member to when the trailing edge of the recording medium passes the transfer nip.

摘要： An image forming apparatus includes a plurality of image carriers and a transfer assembly. The transfer assembly includes a plurality of transferees, a supporter, and a plurality of transferee holders. The plurality of transferers is each configured to electrostatically transfer a toner image carried on one of the image carriers onto an intermediate transfer member or a recording medium. The supporter is configured to support the transferers. The transferer holders are each configured to hold one of the transferers. Each of the transferee holders and the transferer held thereby form an integrated individual unit independently attachable to and detachable from the supporter.

摘要： After an image forming operation is finished, a motor that drives a belt is stopped after a predetermined time period passes since a sensor detects the only one mark provided on the belt. The predetermined time period is different for first, second and third job. This is repeated for the jobs thereafter. One job is a series of processing from the start of the motor to the stop of the motor. Thus, the belt stops at three different position for each consecutive three jobs.
