摘要： A transfer device includes a transfer belt, a transfer roller and a tension roller over which the transfer belt is passed in a tensioned condition and which is made to be in an electrically floated state; it also includes a guide member that is installed in the vicinity of the tension roller. A control section, in transfer processing, controls a first switch so that the guide member is in a grounded state while controlling a second switch so that an electric current being caused to flow to the transfer roller becomes a first electric current; and in cleaning processing, controls the first switch so that the guide member is in an electrically floated state while controlling the second switch so that an electric current being caused to flow to the transfer roller becomes a second electric current.

摘要： For an electrostatic latent image formed on an image carrier (31b), besides an operation forming an “image forming electrostatic latent image” used to form the primary image, an operation is executed that forms an “electrostatic latent image for removing developer” for removing developer that resides on a developer supply member (53a) for a predetermined time period onto the image carrier (31b). Thus, developer is nearly eliminated from residing on this developer supply member (53a) in an overcharged state for a long period of time, and generation of a fogged image is avoided as much as possible.

摘要： A cleaning blade for removing residual toner left on the surface of an intermediate transfer belt after the second transfer is supported integrally with movement of a tension roller. In the case where the tension roller moves to make a tension of the intermediate transfer belt constant, then, following this, the cleaning blade moves. Thus, the contact state of the cleaning blade with respect to the surface of the intermediate transfer belt is kept constant, and thus cleaning of the intermediate transfer belt can be performed stably.

摘要： A transfer device has a control circuit. The control circuit initiates supplying transfer power to one or more first transfer rollers and to a second transfer roller when a first transfer operation is initiated by a first transfer roller positioned most upstream with respect to a direction in which an intermediate transfer belt travels. The control circuit stops supplying the transfer power to the one or more first transfer rollers and to the second transfer roller when a second transfer operation is completed by the second transfer roller. The transfer power supplied to the one or more first transfer rollers and to the second transfer roller, respectively, is free from fluctuation during a period from the initiation of the first transfer operation performed first to the completion of the second transfer operation.

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.
