Abstract: The present invention relates to a driving unit capable of implementing a long stroke drive while achieving height reduction of the driving unit. The driving unit is provided with a driving mechanism for driving a driven body. The driving mechanism includes: a bendable displaceable member that is fixated at one end and, through electric control, bent and displaced at the other end; a driving direction-changing member changing a direction of the bending and displacement of the bendable displaceable member to a driving direction of the driven body, the driving direction of the driven body being perpendicular to the direction of the bendable displaceable member; a contact member frictionally engaged with the driving direction-changing member and driving the driven body; and a precompression member mounted in the driven body and precompressing the contact member towards the driving direction-changing member.

Abstract: A sheet conveying device includable in an image forming apparatus that uses a method of conveying a conveyance target medium and a method of forming an image, includes a position detector, a position adjuster, and circuitry. The position detector is configured to detect a position of a conveyance target medium. Based on a detection of the position of the conveyance target medium by the position detector, the position adjuster moves in at least one of a width direction of the conveyance target medium and a rotation direction of the conveyance target medium within a plane of conveyance of the conveyance target medium and repeatedly adjusts the position of the conveyance target medium while conveying the conveyance target medium. The circuitry changes a conveying speed of the conveyance target medium, according to a change of the position of the conveyance target medium after adjusted by the position adjuster.
