摘要： An image forming apparatus includes an image forming device, a reading device, and processing circuitry. The image forming device forms a first image on a first face of a recording medium and form a second image on a second face of the recording medium. The first face and the second face are on opposite sides of the recording medium. The reading device detects a shape of the recording medium. The processing circuitry corrects the second image to be formed on the second face of the recording medium with respect to the first image formed on the first face of the recording medium based on the shape of the recording medium.

摘要： An image forming apparatus includes a photoconductor that bears an image and an intermediate transfer device that forms a primary transfer nip between the photoconductor and the intermediate transfer device. The intermediate transfer device primarily transfers the image from the photoconductor onto the intermediate transfer device at the primary transfer nip. A secondary transfer device forms a secondary transfer nip between the intermediate transfer device and the secondary transfer device. The secondary transfer device secondarily transfers the image from the intermediate transfer device onto a recording medium at the secondary transfer nip. At least one support shaft supports the intermediate transfer device. The at least one support shaft supports, on an identical axis, one lateral end and another lateral end of the secondary transfer device in a width direction of the recording medium.

摘要： An image reading device includes a first scanner, a second scanner, and circuitry. The first scanner is configured to read a first side of a recording medium. The second scanner is configured to read a second side of the recording medium. The circuitry is configured to generate a first correction value to correct misalignment between the first side and the second side. The circuitry is configured to input a second correction value. The circuitry is configured to correct an image based on the first correction value and the second correction value.

摘要： An image forming apparatus includes a belt unit and a detector unit including a detector that is disposed opposite a tension roller via a belt and a detector support that supports the detector. The detector support includes a first lateral end portion that is disposed at one lateral end of the detector support in an axial direction of the tension roller and is movably attached to an apparatus body. The detector support further includes a second lateral end portion that is disposed at another lateral end of the detector support in the axial direction of the tension roller and is attached to the apparatus body. The first lateral end portion includes an engaging groove that engages a shaft of the tension roller. The engaging groove has a mouth that is disposed at a downstream end of the engaging groove in a detaching direction of the belt unit.

摘要： A unit accommodation apparatus includes a first unit and a second unit that are to be installed into and removed from an apparatus body through an opening in an installation-removal direction and are held by a unit holder. The unit holder includes a first positioner that is disposed opposite one lateral end of the first unit and the second unit and is detachably attached to the first unit and the second unit. A second positioner is disposed opposite another lateral end of the first unit and the second unit and holds the first unit and the second unit in a state in which the first unit and the second unit are detachably attached to the second positioner. The first positioner and the second positioner secure a relative position of the first unit relative to the second unit in a direction parallel to a hypothetical orthogonal plane perpendicular to the installation-removal direction.
