Fixing apparatus for e.g. copier, laser printer used in small personal computer

摘要

The apparatus has a heater (2) provided on the side surface of a heating roller (1) heated to a predetermined temperature when erasing a printed image from a paper. A pressure roller (4) is used to crimp the printing paper to the heating roller. A temperature sensor (3) detects the initial temperature of the heating roller at the start of printing and determines whether the initial temperature is within a first temperature range or a second temperature range. A control unit (32) selects the control system that will be used in controlling the heating of the heating roller based on what temperature range the initial temperature of the heating roller lies.
