摘要： A transfer device includes an image bearer and a transfer rotator. The transfer device further includes an adjuster including a rotatable cam and an opposed member opposed to the cam. The cam alternately contacts and separates the transfer rotator against and from the image bearer, having a continuous sloped surface with a plurality of positions, each position to contact the opposed member to obtain a different amount of separation between the image bearer and the transfer rotator. The transfer device further includes a controller to control the adjuster to adjust the amount of separation between the transfer rotator and the image bearer according to thickness or type of the recording medium when the recording medium starts to enter the transfer nip.

摘要： An image forming apparatus includes an image bearer, a nip forming device, a contact-and-separation device, a thickness information retrieving device, and a controller. The contact-and-separation device moves the image bearer and the nip forming device to contact and separate from each other. The controller controls the contact-and-separation device based on information on a thickness of a recording medium obtained by the thickness information retrieving device such that in a case in which a thickness of a preceding recording medium and a thickness of a successive recording medium are different in continuous printing in which a plurality of recording media is printed out continuously, the contact-and-separation device adjusts a space between the image bearer and the nip forming device when the preceding recording medium exits the transfer nip to a preset size corresponding to the thickness of the successive recording medium that enters the transfer nip.

摘要： A belt device includes a belt assembly, a pressing force adjuster, and an optical sensor. The belt assembly includes multiple rollers and a belt stretched by the multiple rollers and is rotatable about a rotation axis of one of the multiple rollers. The pressing force adjuster rotates the belt assembly about the rotation axis and adjusts a contact pressure of the belt pressed against an object. The optical sensor is disposed opposite to the one of the multiple rollers, and a position of the optical sensor relative to the rotation axis is fixed while the belt assembly is rotated by the pressing force adjuster.

摘要： A pressing device includes an intermediate transfer unit, a secondary transfer unit, a presser, and a drive transmitter. The intermediate transfer unit transfers and conveys a toner image. The secondary transfer unit faces the intermediate transfer unit to form a nip portion between the secondary transfer unit and the intermediate transfer unit and transfers the toner image onto a conveyed material at the nip portion. The presser applies a pressing force for pressing the secondary transfer unit to the intermediate transfer unit at the nip portion. The drive transmitter transmits the pressing force and a conveyance driving force to a driven transmitter of the secondary transfer unit, is restricted in position by the presser, and is movable together with the presser.

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.
