An image forming apparatus includes: a paper feeding part that houses a medium to be fed; a belt-shaped image holding part that holds an image on a surface of the image holding part and rotates; a transfer part disposed to face the image holding part and transfers an image onto a medium from the image holding part in a final transfer region; and a cleaning part that removes a deposit on the surface of the image holding part passed through the final transfer region, in which a downstream side of the paper feeding part in a transport direction of a medium is inclined to be closer than an upstream side of the paper feeding part to the final transfer region, and the image holding part is inclined upward on a downstream side of the final transfer region toward the downstream side in a rotation of the image holding part.

Image forming apparatus

An image forming apparatus includes a transport member that transports a continuous medium as a result of a transport surface of the transport member making contact with the continuous medium and a transfer device that is disposed on a downstream side in a direction in which the transport member transports the medium and that transfers an image onto the medium, which extends to the transport member, as a result of a transfer surface of the transfer device making contact with the medium. A moving speed of the transfer surface is lower than a moving speed of the transport surface when the medium is transported.

A cleaning device includes a cleaning unit that cleans an object to be cleaned that moves by bringing a contact portion into contact with the object to be cleaned, the contact portion extending in a width direction that crosses a moving direction in which the object to be cleaned moves, the cleaning unit including a supported surface at a downstream side in the moving direction; and a support unit including a supporting surface that faces the supported surface and that includes a bonded portion bonded to the supported surface, the support unit supporting the cleaning unit at the bonded portion. The bonded portion is provided at an intermediate position of the supporting surface in a direction in which the supporting surface extends toward the object to be cleaned, and the support unit includes an extending portion that extends further toward the object to be cleaned from the bonded portion.

Cleaning device and image forming apparatus

An image forming apparatus includes an image holding body, a transfer member, and a controller. The image holding body holds an image formed of toner. The transfer member is brought into contact with a continuous medium so as to transfer the image held by the image holding body to the continuous medium, and the transfer member is able to be brought into contact with and separated from the image holding body. The controller causes the transfer member to be separated from the image holding body, and after that, causes the image holding body to move so as to detect an inspection image formed on the image holding body, thereby adjusting, as image quality adjustment, a deviation of a position of the image or a deviation of density of the image to be formed.

Image forming apparatus with controller controlling fixing and transfer members

An image forming apparatus includes plural first transfer units, a second transfer unit, a first transport unit, and a drive unit. The first transfer units transfer an image formed on plural image holding units to an intermediate transfer unit. The second transfer unit transfers the image, which is transferred to the intermediate transfer unit, to a recording medium. The first transport unit transports the recording medium to the second transfer unit. The drive unit drives the intermediate transfer unit with at least some of the plural first transfer units separated from the intermediate transfer unit and with the second transfer unit contacting the intermediate transfer unit when the recording medium, which has been subjected to a transport failure, is transported to a feeding position by the first transport unit.

Image forming apparatus capable of transporting jammed recording medium

An image forming apparatus includes an image holding body, a transfer member, and a controller. The image holding body holds an unfixed image. The transfer member presses a continuous medium against the image holding body and causes the image to be transferred to the medium. The controller allows a cleaning operation in which undesired adhering matter adhering to the transfer member is transferred to the image holding body to be performed when the medium does not exist between the image holding body and the transfer member.

An image forming device includes an image carrier carrying an image, a transfer device including paired transfer members that transport the image carrier and a recording medium, a grounded guide member that guides the recording medium to a transfer region, and a transfer power source that produces an electric field in the transfer region causing the image to be transferred onto the recording medium. The transfer power source includes a first transfer power source that imparts a first transfer voltage to one of the paired transfer members, and a second transfer power source that, when the recording medium has a predetermined resistance value or less, or is of low resistance having a conductive layer along a medium substrate face, imparts a second transfer voltage of opposite polarity and having an absolute value less than or equal to the first transfer voltage to the other of the paired transfer members.
