Claims

[Scope of utility model registration request]

An image forming apparatus in which a thermal fixing device, in which an upper fixing case is openably and closably connected to a lower fixing case, is provided in a lower case of an image forming apparatus main body, in which an upper case of the image forming apparatus main body is openably and closably connected. When the upper case of the main body is opened, the upper fixing case is opened when the temperature of the heat fixing device is below a predetermined temperature, and the upper fixing case is closed when the temperature of the heat fixing device exceeds the predetermined temperature. In addition to providing an opening/closing means for placing the
A danger display means is disposed near the heat fixing device to indicate that the heat fixing device is thermally dangerous when the upper case of the main body of the image forming apparatus is open and the temperature of the heat fixing device exceeds a predetermined temperature. An image forming apparatus comprising:
