DOUBLE FIXING METHOD AND DEVICE IN LASER BEAM PRINTER

摘要

PURPOSE: A double fixing method and device in a laser beam printer is provided to give sufficient pressure and temperature to paper to be fixed by changing the structure into a structure having plural fixing units. CONSTITUTION: A fixing method having an electronograph-developing method has plural circuits to compensate for temperature and pressure in high-speed printing of the electronograph-developing method. A printing device having the electronograph-developing method comprises more than two fixing units(200,202) to compensate for temperature and pressure in high-speed printing of the electronograph-developing method. The fixing unit each comprise a heater roller(1) and a backup roller(3).
