Heating device, fixing device, drier, laminate processing apparatus, and image forming apparatus

A heating device, comprising:

• an endless belt;
• a heater including a base and a heat generator;
• a pressure roller to press the endless belt toward the heater while the heating device is in a pressuring state;
• a flange, including a beam, wherein the flange is disposed at an end of the endless belt, and the flange rotatably supports the endless belt;
• a temperature detector to detect a temperature, the temperature detector disposed inside the endless belt;
• a lead wire connected to the temperature detector, the lead wire extending from an inside of the endless belt to an outside of the endless belt through an inside of the flange, wherein the inside of the flange is a side surrounded by the beam and the other surface of the flange;
• a heater holder to hold the heater;
• a stay to support the heater holder, the stay extending to at least the inside of the flange and to outside of the endless belt;
• and
• a backlash which is between the flange and one of the heater, the heater holder, and the stay, while the heating device is in a non-pressuring state, wherein
• the backlash is smaller than a diameter of the lead wire.
