Fixing device and image forming apparatus

A fixing device comprising:

• an endless belt;
• a fixing rotating body that contacts with and separates from the belt and fixes, in cooperation with the belt, an image formed on a recording medium nipped between the fixing rotating body and the belt while rotating in contact with the belt;
• a support member provided on an inner side of the belt so that the belt slides on the support member during circulation, the support member supporting a load provided when the fixing rotating body is in contact with the belt so as to form a nip portion where the recording medium is nipped between the belt and the fixing rotating body;
• a guide member opposing an outer peripheral portion of the belt on a downstream side of the nip portion in a circulating direction of the belt, the guide member guiding the recording medium to separate the recording medium from the belt after the recording medium passes through the nip portion;
• and
• a moving unit that moves the guide member away from the belt along with separation of the fixing rotating body from the belt,
• wherein the moving unit includes an intermediate member that is supported movably relative to the support member and is moved relative to the support member along with separation of the fixing rotating body from the belt so as to move the guide member away from the belt, and a biasing member that biases the intermediate member relative to the support member so as to move the guide member away from the belt.
