摘要： An image forming apparatus includes a guiding unit. This guiding unit is located between a transferring unit and a fixing unit and includes a guiding part. The guiding part guides a recording sheet from the transferring unit to the fixing unit with a side opposite to the surface of the recording sheet contacting with the guiding part. The guiding part has a greater height at end portions than at a central portion thereof.

摘要： 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.
