Fixiergerät mit Temperaturregelung.

摘要

A fixing apparatus detects the surface temperature of a heat roller (10), detects the temperature of a press roller (30) which press-contacts the heat roller (10) and incorporates a heater (31) or the temperature of an external heating apparatus (30) heating that heat roller (10) from exterior, controls the heater (31) of the above mentioned press roller or the above mentioned external heating apparatus (30) based on the results of these detections, and thereby performs a high-quality fixing operation without damaging the heat roller (10).
