It separates a member pressing against the surface of the rotating member to separate the recording medium from the rotating member and its contact pressure is switchable between the first and second pressure, the second pressure being less than the first pressure and the switching taking place during the separation of the recording medium from the rotating member and after a front edge of the recording medium has separated.
