Abstract: A neutralization unit for use in an image forming apparatus includes a support member made of an insulating material, an electric-charge removing member made of an electric conductive material, and a rib made of an insulating material. The electric-charge removing member, fixed on the support member, removes electric charge from a back face of the recording medium after a toner image is transferred to a front face of a recording medium at a transfer nip. The electric-charge removing member includes a plurality of exposed areas along a longitudinal direction of the electric-charge removing member. The rib, provided on the support member, has a curved peripheral side and protrudes from a surface of the electric-charge removing member. The back face of the recording medium is contactable at the curved peripheral side of the rib when the recording medium is transported from the transfer nip.

The slidable member is co-movably coupled with the roller shaft to define a second interfacial surface therealong inclined relative to the axial direction. The biasing mechanism is connected to the roller shaft to press the slidable member against the stationary member.

Abstract: 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.
