摘要： A transfer belt is driven by a plurality of supporting rollers. A unit frame supports the supporting rollers in a rotatable manner. At least one of the supporting rollers includes a cylindrical member having a substantially same outer diameter over an entire length thereof. Each end portion of the cylindrical member in a longitudinal direction is supported by the unit frame via a bearing in a rotatable manner.

摘要： An image forming apparatus includes an image carrier, a transferor, a fixing unit, and a guide. The image carrier carries a toner image. The transferor opposes the image carrier to form a transfer nip and transfers the toner image on the image carrier onto a recording medium at the transfer nip. The fixing unit fixes the toner image on the recording medium. The guide guides the recording medium bearing the toner image from the transferor toward the fixing unit and includes a surface portion directly contacting the recording medium. The surface portion includes a material for charging the recording medium to have a polarity opposite to the polarity of a toner forming the toner image.

摘要： An image forming apparatus includes at least one image carrier and a recording medium conveyor forming a transfer nip therebetween, a conveyance member disposed closest to the transfer nip on an upstream side of the transfer nip to convey the recording medium to the transfer nip, and a conveyance control mechanism to deactivate the conveyance member to stop providing a conveyance force to the recording medium after the leading edge of the recording medium has entered the transfer nip and before the trailing edge of the recording medium passes a point of force application and remaining in the inactive state until the recording medium passes the point of force application. The conveyance force remains unapplied to the recording medium from when the conveyance control mechanism deactivates the conveyance member to when the trailing edge of the recording medium passes the transfer nip.

摘要： An image forming apparatus includes a plurality of image carriers and a transfer assembly. The transfer assembly includes a plurality of transferees, a supporter, and a plurality of transferee holders. The plurality of transferers is each configured to electrostatically transfer a toner image carried on one of the image carriers onto an intermediate transfer member or a recording medium. The supporter is configured to support the transferers. The transferer holders are each configured to hold one of the transferers. Each of the transferee holders and the transferer held thereby form an integrated individual unit independently attachable to and detachable from the supporter.
