Abstract
An image heating apparatus includes a first member; a second member for forming a nip in cooperation with the first member; a first frame for supporting the first frame a second frame connected to the first member frame rotation about a rotational axis; a first pressing member for pressing the second member toward the first member, away from the second frame; and a second pressing member for applying an additional pressure between the first and second frames so that an additional pressure is applied between the first and second member.
Claims17
An image heating apparatus comprising:
- a first member;
- a second member for forming a nip in cooperation with said first member;
- a first frame for supporting said first member;
- a second frame connected to said first frame for rotation about a rotational axis;
- a first elastic member having an elastic force for pressing said second member toward said first member from said second frame;
- and
- a second elastic member for imparting pressure between said first frame and said second frame to increase the elastic force of said first elastic member, said second elastic member being located at a position away from said first elastic member in a direction away from said rotational axis.
