PURPOSE:To effectively provide erasing properties by forming an information erasing member of a plurality of heat generators, and so forming the generators as to independently regulate temperatures in a heater for a printer, etc. CONSTITUTION:An erasing member 21 is formed of a protective layer formed with metal oxide on a ceramic board 35, and the oxides are formed on surface heat generators 56-1-56-3. A board 55 is divided into a plurality of bases 58, the generators 56-1-56-3 are respectively formed on the bases 58 as the independent generators 56-1-56-3. The generators 56-1-56-3 are connected at electrode parts 59 to heat generating drivers 64 through electrodes 63. The drivers 64 are connected to a CPU 65, and controlled by the CPU 65. A temperature of the member 21 is detected by a sensor, and the CPU 65 independently controls the generators 56-1-56-3 based on the detected temperatures through the drivers 64. |
