When L1 is defined as a Rockwell hardness of a sliding portion-side surface of the belt and L2 is defined as a Rockwell hardness of a belt-side surface of the sliding portion, a hardness ratio L2/L1 is 0.8 or more and 1.4 or less.
Claims6
A fixing device for fixing a toner image formed on a recording medium, the fixing device comprising:
- a belt that conveys the recording medium;
- a support that supports the belt;
- a facing member that is disposed to face the support with the belt interposed between the facing member and the support and forms a nipper that applies pressure to the belt and the recording medium between the facing member and the support;
- and
- a slider on which the belt slides at a pressure lower than that of the nip portion, wherein
- when L1 is defined as a Rockwell hardness of a surface of the belt and L2 is defined as a Rockwell hardness of a surface of the slider, a hardness ratio L2/L1 is 0.8 or more and 1.4 or less, the surface of the belt being located on a side of the slider, the surface of the slider being located on a side of the belt.
