    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 translation: 图像形成装置包括图像载体，转印器，定影单元和引导件。 图像载体携带调色剂图像。 转印器与图像载体相对以形成转印压区，并将转印辊上的图像载体上的调色剂图像转印到记录介质上。 定影单元将调色剂图像固定在记录介质上。 引导件将从转印器承载调色剂图像的记录介质引向定影单元，并且包括直接接触记录介质的表面部分。 表面部分包括用于将记录介质充电以具有与形成调色剂图像的调色剂的极性相反的极性的材料。

    Abstract: An image forming apparatus that has improved usability, while maintaining good positional relationship of units detachably installed inside the apparatus body. The image forming apparatus includes a plurality of rotatable image carriers, each incorporated in a respective image producing unit, and an intermediate transfer unit including an intermediate transfer body which is installed between a plurality of roller members and to which transfer toner images formed on each image carrier are transferred. The shaft of each image carrier and the shaft of each roller are disposed on a positioning plate, and each image carrier and the intermediate transfer body are fixed in normal positions by applying pressure independently to each shaft.

    Abstract: An image forming apparatus of the present invention includes a pair of support plates supporting the rotary shaft of a photoconductive drum at axially opposite ends of the drum. One of the support plates is openable away from the body of the apparatus and loaded with a contact forming member including a current feed path for feeding a current from a high-tension power supply for charging to a charge roller, a wiring forming a current return path that allows a current to flow from the photoconductive drum to the ground of the power supply, and a plurality of contacts where the wiring and drum contact each other. A current flowing through the current return path is sensed to execute feedback control to the output of the high-tension power supply.
