Abstract:
A fixing apparatus comprising:a fixing rotator in contact with a recording material supporting an unfixed image; a pressure rotator in pressure contact with said fixing rotator; a support member supporting said pressure rotator and swingable around a plurality of fulcrums; an elastic member for biasing said support member so that said pressure rotator is biased to said fixing rotator; and pressure contact force changing means for changing a pressure contact force by swinging said support member against a biasing force of said elastic member, wherein said pressure contact force changing means can change the pressure contact force while said pressure rotator is in pressure contact with said fixing rotator, and wherein a position of the fulcrums is variable in a direction intersecting with a pressure contact force direction in accordance with a condition of activation to said support member by said pressure contact force changing means.
