Image forming apparatus with electrically grounded roller
 An image forming apparatus includes an image bearing member for carrying a toner image; a recording material conveyer belt for electrostatically carrying and feeding a recording material; a roller, provided on a side of the recording material conveyer belt not carrying the recording material in a separation position where the recording material is separated from the recording material conveyer belt, for supporting the recording material conveyer belt; a transfer charger for electrostatically transferring the toner image from the image bearing member onto the recording material at a transfer position; a discharge, provided across the recording material conveyer belt from the roller at the separation position, for discharging the recording material upon separation thereof from the recording material conveyer belt; wherein the roller is electrically grounded through an element in which a voltage is generated when the current is supplied thereto.
