ABSTRACT:
An image forming apparatus includes an intermediary transfer member for primary-transferring the toner at a primary transfer position so that a second color toner image is primary-transferred from an image carrying member onto a first color toner image which has been transferred in a superposition manner; a secondary transfer member for secondary-transferring the first and second color toner images together from the intermediary transfer member onto a recording; a fixing apparatus for fixing the toner images on the recording material; a guide member for guiding the recording material to the fixing apparatus; an electrical discharging member, for electrically discharging the recording material onto which the toner images are secondary-transferred; and a voltage application apparatus for applying, to the electrical discharging member before the secondary transfer, a voltage of a polarity identical to that of the first color toner image on the intermediary transfer member at a predetermined period.
