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： A roller device that can be exchangeably used in an image forming apparatus includes a roller, a shaft, and two grip members. The roller is configured to cover the shaft along the rotation axis and have two roller ends from which the two shaft end portions of the shaft are projected outwardly along the rotation axis. A shaft is configured to have a rotation axis at a center thereof and have two shaft end portions. The two grip members are each configured to be rotatably disposed to a respective shaft end portion of the two shaft end portions.

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： A static eliminator includes a plurality of static eliminating needles, a holder including a retaining surface on which the plurality of static eliminating needles is held, a plurality of partitions, and a restriction member including a first end portion having a restriction surface at a static eliminating needle side to contact the static eliminating needles. A length of the plurality of static eliminating needles from the first end portion of the restriction member as an origin to a leading end of the plurality of static eliminating needles is shorter than a distance from the origin to an end surface of the plurality of partitions within the range of movement of the plurality of static eliminating needles from the retaining surface up to a position five degrees (5°) below the restriction surface in an angle between the retaining surface and an imaginary plane including the restriction surface.
