    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.

    Abstract: An image forming apparatus forms a multiple-color image with at least two process speeds. A secondary-transfer-bias applying unit applies a bias to a secondary transfer unit at a non-image-formation time. A secondary-transfer-output detecting unit detects an output value with respect to each of the at least two process speeds. A secondary-transfer-bias control unit determines a secondary transfer bias to be applied to the secondary transfer unit based on the output value detected.

    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.
