ABSTRACT:
An image forming apparatus has an image supporting member for supporting a toner image, a transfer rotating member forming a nip with the image supporting member and electrostatically transferring the toner image formed on the image supporting member to a recording material, a fixing device for fixing the toner image to the recording material holding the toner image, and a guide member for guiding the recording material so that the angle between the direction of separation of the recording material from the transfer rotating member and the tangent to the image supporting member at the center of the nip is at least 2.degree. in a direction toward the image supporting member. The fixing device has a fixing rotating member, which contacts the toner image on the recording material and to which a bias of the same polarity as that of the toner is applied, and a pressure rotating member in pressure contact with the fixing rotating member so as to hold the recording material between the fixing rotating member and the pressure rotating member.
