ABSTRACT:
To ensure stable feed of transfer material when a paper back vacuuming feed mechanism is employed in the path from a transfer section to a fixing section in an image forming apparatus, the image forming apparatus is such that the transfer section is arranged on the upper surface of the intermediate transfer unit; a transfer material feed apparatus is provided for vacuum feeding transfer material from the transfer section to the fixing apparatus; a guide tilted by a predetermined angle downward of the transfer material feed surface is provided at the outlet of the fixing apparatus of the transfer material feed apparatus; the nip portion of a fixing roller pair of the fixing apparatus is positioned downward of the extension line of the guide; and the tangent with respect to the nip portion of the fixing roller is tilted by a predetermined angle downward of the transfer material feed surface.
