    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.

    Abstract: A cleaning device is used in an image forming apparatus to remove residual attachments including toner and paper powders from a surface of a movable intermediate transfer element onto which toner images are transferred from an image carrier. The cleaning device includes a cleaning brush that contacts the surface of the intermediate transfer element to apply a bias having a predetermined polarity to the toner adhered onto the surface of the intermediate transfer element so as to make uniform a polarity of the toner. The cleaning device further includes a pressing member that contacts the surface of the intermediate transfer element with a predetermined pressure. The pressing member is disposed at a position upstream of the cleaning brush in a direction of movement of the intermediate transfer element.

    Abstract: An image forming apparatus includes an intermediate transfer belt, a photosensitive belt, a primary transfer roller, a secondary-transfer opposing roller, and a secondary transfer roller. The photosensitive belt comes into contact with a surface of the intermediate transfer belt to form a primary transfer nip. The secondary-transfer opposing roller comes into contact with the surface of the intermediate transfer belt to form a secondary transfer nip. The closest distance between a surface of the photosensitive belt and that of the primary transfer roller is greater than the thickness of the intermediate transfer belt. A toner image on the intermediate transfer belt is transferred onto a recording sheet at the secondary transfer nip while a transfer bias is applied to the secondary transfer roller.
