    摘要： A load torque variation upon entry or exit of a sheet into a nipping portion is reduced while a nipping force necessary for image formation is provided. An image transfer apparatus, an image fixing apparatus, or a registration apparatus comprises an opposite roller, a transfer roller, and a compression spring for pressing the opposite roller onto the transfer roller. A sheet of transfer material is transported into a nipping portion between the opposite roller and the transfer roller, where an image on the opposite roller is transferred to the transfer material. The apparatus includes a retaining unit configured to retain a certain distance between the first rotating body and the second rotating body as long as the thickness of the transfer material that passes through the nipping portion remains the same.

    摘要： A sheet conveying device, that can be included in an image forming apparatus, includes a drive source, a drive roller driven by the drive source, a driven roller to press against the drive roller and rotate with the drive roller, an angular velocity detector to detect an angular velocity of the drive roller, a timing estimation unit to estimate a timing when a sheet-type recording medium enters between the drive roller and the driven roller, and a controller to control the drive source based on detection results obtained by the angular velocity detector. The controller includes a feedback control unit to perform feedback control based on data obtained by the angular velocity detector, and a feed-forward control unit to perform feed-forward control based on data obtained by the timing estimation unit.
