    Abstract: A transfer device, which transfers an image onto a recording medium directly or indirectly and is included in an image forming apparatus, includes an endless belt member extended between a drive roller rotated and a driven roller and configured to receive the image from the image carrier part onto either a surface thereof or the recording medium carried on the surface thereof while moving according to rotations of the drive roller, and a rotation speed detector configured to detect a rotation speed of the driven roller. An image detector is provided either to the transfer device or to the image forming apparatus to detect the image formed on the endless belt member directly or the recording medium carried on the endless belt member, and disposed facing the driven roller in a circumferential direction of the endless belt 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.

    Abstract: One end of a rotational shaft of a supporting rotational body attached with a rotational member is rotatably supported. The rotational member is sandwiched by a supporting frame that rotatably supports supporting rotational bodies spanned with an annular belt and fixing members fixed to the supporting frame. Thus, the one end of the rotational shaft is supported by the supporting frame and the fixing members at, at least two points. A mark detector is fixed to the fixing members, and the fixing members are fixed to the supporting frame at, at least two points. Accordingly, erroneous detection of a rotational angular speed or a rotational angular displacement of a supporting rotational body due to vibration of the supporting rotational body can be suppressed.
