Claim:
1. An image forming apparatus, comprising: an image carrier that carries a toner image; a conveyance belt in contact with the image carrier to form a nip, the conveyance belt conveying a sheet via the nip position; a transfer roller to which a voltage of reversed polarity to a charge polarity of toner forming the toner image is applied, so as to transfer the toner image to the sheet at the nip position; a suspension roller that suspends the conveyance belt at a separation position, the separation position being downstream with respect to the nip position in a sheet conveyance direction, the separation position being positioned where the sheet separates from the conveyance belt, the voltage of reversed polarity to the charge polarity of the toner being applied to the suspension roller; a conductive opposed member arranged opposed to the suspension roller across the conveyance belt; a housing that internally houses the image carrier to carry the toner image; an open/close cover that covers an opening so as to be openable/closable, the opening being formed on a side surface of the housing; an image carrier protection member that moves to a protection position in association with an open operation of the open/close cover to cover the open/close cover side of the image carrier, the image carrier protection member moving to an open position in association with a close operation of the open/close cover to open the open/close cover side of the image carrier; a suspension roller power supply unit that applies the voltage of the reversed polarity to the charge polarity of the toner to the suspension roller; and a protection member power supply unit that applies the voltage of the reversed polarity to the charge polarity of the toner to the image carrier protection member.
