Transferring device and image forming apparatus

摘要

A transferring device includes a conveying belt, a transferring roller, a stretching roller and a guide member. The conveying belt comes into contact with an image carrier carrying a toner image and conveys a sheet via a contact position to the image carrier. The transferring roller takes applying of voltage with a reversed polarity to a charged polarity of the toner forming the toner image and transfers the toner image carried on the image carrier onto the sheet at the contact position. The stretching roller stretches the conveying belt at a downstream side from the contact position in a conveying direction of the conveying belt and at a separation position of the sheet separated from the conveying belt. The guide member is arranged at a position facing to the sheet conveyed from the stretching roller to a fixing device to take applying of the voltage with the reversed polarity.

主权项

1. A transferring device comprising:
a conveying belt arranged so as to face to an image carrier carrying a toner image and to contact the image carrier and convey a sheet via a contact position therebetween; a transferring roller, to which a voltage with a reversed polarity to a charged polarity of the toner forming the toner image is applied, transferring the toner image carried on the image carrier onto the sheet at the contact position; a stretching roller stretching the conveying belt at a downstream side from the contact position in a conveying direction of the conveying belt and at a separation position, where the sheet is separated from the conveying belt; and a guide member, to which the voltage with the reversed polarity to the charged polarity of the toner is applied, arranged at a position facing to the sheet conveyed from the stretching roller to a fixing device fixing the toner image onto the sheet.
