摘要： The contact rate between a heater 1 and a heater holder 2 is made higher at both ends in the longitudinal direction of the heater than at the center. Alternatively, the per-unit-length volume of the heater holder 2 in the longitudinal direction is made larger at the both ends in the longitudinal direction of the heater. In this configuration, the heat generated by the heater can easily escape into the heater holder side at the both ends but cannot easily escape into the heater holder side at the center. Although the per-unit-length heat amount in the longitudinal direction of the heater 1 may be even, it is also possible to set the heat amount distribution in such a way that the heat amount at the both ends is larger than that at the center. The present invention prevents an improper fixing problem generated by an insufficient temperature at a particular position of a recording material and, at the same time, prevents an increase in the temperature of the non-paper-passage part that occurs when a narrow recording material is used.
