摘要： A tandem-type image forming apparatus for forming a multi-color image on a sheet transported by an endless transfer/transport belt, by sequentially laying on the sheet images developed in respective image forming stations. The apparatus includes: transfer rollers, each in contact through the transfer/transport belt with an image carrier provided in each image forming station; and a voltage applying device for applying a non-transfer bias voltage to only the transfer rollers that are in contact with the image carriers when a transfer process is not performed, the non-transfer bias voltage having the same polarity as a transfer bias voltage and being lower than the transfer bias voltage.

摘要： An image forming apparatus is provided with a latent image carrier for holding an electrostatic latent image, and an intermediate transfer member for temporally holding an image formed by visualizing the electrostatic latent image formed on the latent image carrier. The image forming apparatus performs image formation by superimposing a plurality of images on the intermediate transfer member so as to form a superimposing image, and transferring the superimposing image on a recording medium. The intermediate transfer member has a latent image holding property for holding the electrostatic latent image. An image formed by visualizing an electrostatic latent image formed on the intermediate transfer member is superimposed with the electrostatic latent image formed on the latent image carrier.

摘要： An image transfer device includes: first and second rollers; and exit-side roller disposed downstream of the second roller; an endless transfer belt tensioned between the first roller and the exit-side roller with the second roller in between so that the part of the transfer belt between the first and second rollers can be kept in contact with a photoreceptor; a conductive, endless voltage supplying belt tensioned between the first and second rollers so as to come in contact with a wide area of the inside surface of the transfer belt. The first roller is applied with a predetermined voltage from a power source so that the voltage is supplied to the transfer range of the transfer belt via the voltage supplying belt. In this arrangement, when a sheet of paper is conveyed into the contact area between the transfer belt and the photoreceptor, a toner image formed on the photoreceptor is transferred to the fed sheet of paper.

摘要： In a fixing device including (i) an external heat belt which abuts against a surface of a fixing roller so as to heat the fixing roller and (ii) a cleaning member which abuts against the external heat belt, a fixing temperature, which is a surface temperature of the fixing roller during a fixing process, is set per group into which recording media to be subjected to the fixing process are divided according to their widths in a direction of a rotary axis of the fixing roller, in such a way that the fixing temperature is set to a lower temperature for a group of narrower widths. This makes it possible to prevent a reduction in releasability of the fixing roller caused by a material, which is scraped off from the external heat belt by the cleaning member and then adhered to the fixing roller, thereby preventing the high-temperature offset.

摘要： An image forming apparatus transfers a toner image formed on a photoconductor drum onto a sheet-like recording member while the sheet-like recording member is transported and attracted to a transfer belt, and comprises a jam handling control unit for detecting a transport fault of the sheet-like recording member, and for stopping the transport operation when the transport fault is detected. When the transport fault is detected in a section other than a fixing section, the jam handling control unit first causes the transport operation of the fixing section, and thereafter causes the transfer belt and the transport operation on the upstream side thereof to stop, and any sheet-like recording member remaining on the transfer belt so that the transport mechanism on the upstream side thereof is transported and stopped at the position spanning between the area of the fixing section and the area of the transfer belt.
