    摘要: A transfer unit includes: an intermediate transfer belt that (i) holds a toner image that has been transferred from a photoreceptor drum and (ii) moves a surface holding the toner image; and a secondary transfer belt that comes into contact with the intermediate transfer belt. The transfer unit (i) transfers the toner image from the intermediate transfer belt to a sheet conveyed to the secondary transfer part and (ii) includes a cleaning unit that removes and collects toner from the surface of the intermediate transfer belt. The transfer unit also includes a power source for sequentially applying, to the secondary transfer belt, (i) a first voltage for generating an electric field that transfers normally-charged toner from the secondary transfer belt to the intermediate transfer belt and (ii) a second voltage for generating an electric field that transfers oppositely-charged toner from the secondary transfer belt to the intermediate transfer belt.

    摘要: A transfer unit includes: an intermediate transfer belt that (i) holds a toner image that has been transferred, at a primary transfer part, from a photoreceptor drum and (ii) rotates to move a surface holding the toner image; and a secondary transfer belt that comes into contact, at a secondary transfer part, with the intermediate transfer belt. The transfer unit (i) transfers the toner image from the intermediate transfer belt to a sheet conveyed to the secondary transfer part and (ii) includes an intermediate transfer belt cleaning unit that removes and collects toner from the toner image holding surface of the intermediate transfer belt. The transfer unit also includes secondary transfer power source for sequentially applying, to the secondary transfer belt, (i) a first voltage for generating an electric field that transfers normally-charged toner from the secondary transfer belt to the intermediate transfer belt and (ii) a second voltage for generating an electric field that transfers oppositely-charged toner from the secondary transfer belt to the intermediate transfer belt. Therefore, the toner from the secondary transfer belt can be suitably transferred to an intermediate transfer belt, and the secondary transfer belt can be desirably cleaned.

    摘要: A junction/disjunction unit of a multicolored image forming apparatus joints/disjoints a transfer material holder with/from an image holder, to switch over between a monochromatic image forming mode which uses a specific image forming unit and a multicolored image forming mode which uses a plurality of image forming units. For switching the image forming mode, a driving unit for driving the junction/disjunction unit also drives an auger provided for conveying toner, which has been recovered by a transfer material holder cleaning unit for recovering toner remaining on the transfer material holder, into a recovery container. Accordingly, a driving force outputted from the driving unit can be effectively utilized, and thereby good cost performance can be realized.

    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.

    摘要: In the present applying mechanism, a part of a guide sheet 33 bulges (arches) away from an oil application roller 16, with respect to a vertical line S passing through the center of a pipe 31. In other words, in the present applying mechanism, a part of the guide sheet 33 has a shape of avoiding (bypassing) the oil application roller 16 that has a high temperature. With this, oil flowing on the guide sheet 33 is kept away from the high-temperature oil application roller 16. The present applying mechanism can include an edge 50, or gap, in the guide sheet 33 for backing-up flow of oil to before the application roller in order to ensure even distribution of the oil to the application roller. The present applying mechanism can include a narrow gap between the pipe 31 and guide sheet 33.
