Abstract: A belt positioning system for positioning a movable belt entrained about a plurality of generally parallel rollers for moving in a trans-axial direction perpendicular to an axial direction in which the rollers extend parallel to each other includes a flange. The flange is operatively connected to an axial end of a specific one of the plurality of generally parallel rollers to define a contact surface therealong which extends generally perpendicular to the axial direction to contact an adjoining edge of the belt. The contact surface of the flange is spaced apart from the axial end of the roller in the axial direction.

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 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.
