A medium transport device includes a transport belt that is disposed in such a manner as to face an image holding unit holding an image and that is capable of moving circularly so as to transport a medium, a first stretching roller that stretches a portion of the transport belt and that is disposed in such a manner as to face the image holding unit, the first stretching roller being configured to transport the medium by nipping the medium between the image holding unit and the transport belt and configured to transfer the image held by the image holding unit onto the medium, a second stretching roller that stretches a portion of the transport belt that is located downstream from the portion of the transport belt stretched by the first stretching roller in a transport direction of the medium, a contact adjusting unit that causes a second end of the first stretching roller in an axial direction of the first stretching roller to swing while a first end of the first stretching roller serves as a fulcrum and adjusts a contact state between the image holding unit and the transport belt in a longitudinal direction of a contact region between the image holding unit and the transport belt, and a position adjusting unit that keeps a distance between the center of the first stretching roller and the center of the second stretching roller constant and adjusts a position of the second stretching roller with respect to the first stretching roller by causing a second end of the second stretching roller to swing while a first end of the second stretching roller serves as a fulcrum.

An image forming apparatus includes a first unit, a second unit, a first adjusting member, and a second adjusting member. The first unit includes an endless first belt member and a first rotating member that rotates while supporting the first belt member. The second unit includes a rotatable second rotating member that opposes the first rotating member with the first belt member interposed therebetween. The first adjusting member is disposed on either one of the first unit and the second unit to adjust a load between the first rotating member and the second rotating member. The second adjusting member is disposed on the other one of the first unit and the second unit to adjust parallelism between the first rotating member and the second rotating member.

Adjusting mechanism of image forming apparatus

A medium transport device includes a transport member and a guide member. The transport member supports and transports a medium. The guide member is shifted from the transport member in a width direction of the medium to guide the medium. The guide member includes contact portions that come into contact with the medium. The contact portions are spaced apart from one another in a transport direction of the medium.

Medium transport device and image forming apparatus

A transfer device includes a transfer unit and an adjustment unit. The transfer unit includes a transfer belt and a transfer roller. The transfer belt is wound around a rotating winding roller to circulate. An image is to be formed on the transfer belt. The transfer roller is disposed on an opposite side of the winding roller across the transfer belt. The transfer roller is configured to transfer the image on the transfer belt to a recording medium. The adjustment unit is configured to change an axial direction of the transfer roller to adjust parallelism between an axis of the transfer roller and an axis of the winding roller.

Transfer device and image forming apparatus

A flywheel includes a rotation shaft, a flywheel body, and a protruding body. A first end of the rotation shaft is supported by a rotating body. The flywheel body is provided at a second end of the rotation shaft and rotates together with the rotation shaft. The protruding body protrudes from a surface at a rotating-body side of the flywheel body and extends in a circumferential direction of the rotation shaft.

Flywheel and image forming apparatus

Provided is a transfer device including a primary transfer roller that selectively takes a contact position where an intermediate transfer belt is brought into contact with an image holding member, and a separation position where the intermediate transfer belt is separated from the image holding member, a tension applying roller on which the intermediate transfer belt is wound thereon together with a driving roller and which is urged in a direction receding from the driving roller, and a relaxing member that is attached to a shaft portion of the tension applying roller, is urged by an urging unit in a direction approaching the driving roller, and relaxes an urging force of the tension applying roller in a direction receding from the driving roller when the primary transfer roller is at the separation position.
