Abstract: An image forming apparatus includes an image bearer, an image forming unit, an intermediate transfer member, a secondary transfer member, an image detector, a computing device, and a conveyor device. The computing device calculates a traveling speed of the intermediate transfer member based on detection information provided by the image detector. The conveyor device continuously transports to a secondary transfer portion a plurality of recording media one by one at a predetermined interval between successive recording media. The image forming unit forms a test image at a space between successive recording-medium contact regions of the intermediate transfer member at which the recording medium contacts the intermediate transfer member. A travel distance of the intermediate transfer member from the detection position on the intermediate transfer member to the secondary transfer portion in a traveling direction thereof is shorter than the space between the successive recording-medium contact regions.

Abstract: A drive transmission device includes a drive transmission member and a rotation shaft. The drive transmission member has an insertion portion. The rotation shaft includes a press-fit portion and another flat portion. The press-fit portion press-fits into the insertion portion after insertion of an axial tip of the rotation shaft into the insertion portion and includes a press-fit flat portion parallel to an axial direction of the rotation shaft. The other flat portion is at a position closer to the axial tip than the press-fit flat portion. The insertion portion has an inner-wall flat portion to contact the press-fit flat portion when the press-fit portion is press-fitted into the insertion portion.

Abstract: A sheet conveying device includes a pair of rollers including a first roller and a second roller to hold a sheet conveyed between the first and second rollers; a biasing member to bias the first roller toward the second roller; a biasing force changer to change a biasing force of the biasing member; control circuitry to, when a predetermined changing condition is met, cause the changer to change the biasing force and cause the rollers to convey the sheet; an operation detector to detect a changing operation of the changer; and a notification device to notify an abnormality of the changing operation when the operation detector detects the abnormality. When the operation detector detects the abnormality, the control circuitry performs sheet conveyance control to cause the rollers to convey the sheet without causing the changer to change the biasing force, regardless of whether the predetermined changing condition is met.

Abstract: A moving device assembly includes a moving device and a shield. The moving device is movable between a first position and a second position, to move a detector including a detection surface relative to an opposing member disposed opposite the detector. The shield shields the detection surface of the detector. As the moving device is at the first position, the detector is at a proximal position at which the detector is near the opposing member, and as the moving device is at the second position, the detector is at a shield position at which the detector is separated from the opposing member and the detection surface of the detector is shielded by the shield.
