Fixing device

A fixing device for heating a toner image born on a recording material and fixing on the recording material, the fixing device comprising:

• an endless belt member;
• a rotatable member configured to rotate in contact with an outer peripheral surface of the belt member;
• a nip portion forming member provided inside the belt member to oppose the rotatable member via the belt member and configured to form a nip portion to nip and convey the recording material between the belt member and the rotatable member;
• a stretching roller configured to stretch the belt member in contact with an inner peripheral surface of the belt member;
• a tension roller in contact with the inner peripheral surface of the belt member;
• a first urging member configured to urge the tension roller toward the belt member and to apply a tension to the belt member by the tension roller;
• a lubricant supplying roller configured to supply a lubricant to the belt member in contact with the inner peripheral surface of the belt member;
• and
• a second urging member configured to urge the lubricant supplying roller toward the belt member,
• wherein the tension roller is movable between a first urging position where the tension roller urges the belt member by the first urging member and a first urge releasing position where the tension roller does not urge the belt member regardless of an urging force of the first urging member,
• wherein the lubricant supplying roller is movable between a second urging position where the lubricant supplying roller urges the belt member by the second urging member in a state in which the tension roller is positioned in the first urging position and a second urge releasing position where the lubricant supplying roller does not urge the belt member regardless of an urging force of the second urging member, and wherein the lubricant supplying roller is moved from the second urging position to the second urge releasing position in interlocking with a moving operation of the tension roller from the first urging position to the first urge releasing position.
