Abstract
An apparatus including: an image forming portion; a recording-material transporting member; a cleaning portion; a fixing portion equipped with a fixing member coated with a mold release agent; and a controller. The apparatus can perform two-sided copying by transferring and fixing an image on a first surface of recording material, and then transferring and fixing an image on an opposite surface. A cleaning blade in the cleaning portion abuts the recording material transport means and a normal line of a surface of the cleaning blade is substantially directed to a gravity direction, and faces an upstream side of an abutting portion of the cleaning blade in a transportation direction of the recording-material transporting member, wherein the surface of the cleaning blade facing an upstream side of an abutting position in a transportation direction faces a direction opposite to the gravity direction.
