Patent JP-H03189674-A (JP)
Title: Fixing device
Inventor: SAWAMURA EIJI
IPC: G03G15/20
Filed: 1989-12-19
Abstract: PURPOSE:To surely prevent the burning of paper and the damage of other contact parts by providing a temperature indicating means provided in a paper non-passing area part and a control means for controlling the energization for a heating means based on a detection signal. CONSTITUTION:A photosensor 106 continues to photograph a temperature indicating paper 105 at any time. Supposing that the color of the temperature indicating paper 105 at a normal time is white, for example, the color thereof is changed from white to brown when a heater 101 runs away and the color change temperature of the paper 105 is attained. The photosensor 106 photographs the change of the color and informs a control part 110. When color information (brown information) is inputted, the control part 110 judges that it is different from the color at the normal time (white) and considers that abnormality occurs, then cuts off the energization of the heater 101. Thus, the energization of the heater is appropriately controlled even in a state where it is completely cool in an electrophotographic copying device and the burning of paper and the damage of other contact parts are surely prevented.
