  • Patent number: 12216428
    Abstract: An image forming apparatus includes a fixing device to heat a recording material at a use position, an opening and closing member, and a drawer unit. In a state where the fixing device is at the use position, part of the fixing device is located in a space for the drawer unit to pass through when moved from a first inner position to a first outer position so that movement of the drawer unit from the first inner to the first outer position is restricted. The fixing device is retracted from the use position to a retracted position so that the movement of the drawer unit from the first inner to the first outer position is allowed. Part of the fixing device at the retracted position is at a position higher than a position of an upper cover portion of the opening and closing member at a closed position.
