    Abstract: One or two auxiliary rollers of relatively small diameter are pressed against the peripheral surface of a main rotatable body which is heated. Where the two auxiliary rollers are employed, they are spaced apart from each other and are rotated in one direction at the same peripheral speed as that of the main rotatable body. A sheet carrying an unfixed toner image is fed by being gripped between the main rotatable body and the auxiliary rollers, during which the toner is heated and dried, and fixed to the sheet with the solvent evaporated. Thereafter, the sheet is discharged toward a next process. The sheet auxiliary sheets are relatively disposed under certain positional conditions for keeping the sheet in intimate contact with the main rotatable body to achieve proper toner fixing and sheet feeding operations.

    Abstract: A surface moving body includes an endless surface that is capable of making an endless movement. A surface-moving-body drive mechanism includes a driving source of a driving force for moving the surface moving body and a drive transmission mechanism for transmitting the driving force from the driving source to the surface moving body. At least a part of the surface-moving-body drive mechanism is arranged in a surface-moving-body occupying space surrounded by two surfaces defined by ends of the endless surface in a width direction orthogonal to a surface moving direction of the endless surface and the endless surface.

    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.
