Fixing device

A fixing device comprising:

• a tubular member;
• a heater having a first surface in contact with an inner surface of the tubular member, the first surface facing in a first direction, and the heater including:
• a substrate including a cut section containing a burr;
• and
• a heating element coupled to the substrate;
• and
• a support including:
• a first projection and a second projection each engaging the inner surface of the tubular member, the heater extending between the first projection and the second projection, and the first projection and the second projection each extending further in the first direction than the first surface;
• and
• a low section adjacent the first projection and engaging the inner surface of the tubular member, the first projection extending further in the first direction than the low section.

An image forming apparatus including:

• a sheet supply containing a sheet;
• a transfer assembly configured to transfer a toner image onto the sheet;
• and
• a fixing device configured to fix the toner image to the sheet, the fixing device comprising:
• a tubular member extending in an axial direction;
• a heater having a first surface in contact with an inner surface of the tubular member, the first surface facing in a first thickness direction,
• the heater including a substrate including a cut section that is manufactured by disconnecting the cut section from a base material, the cut section being positioned at an end portion of the substrate in a first lateral direction, the substrate extending longitudinally along the axial direction;
• and
• a support in contact with the inner surface of the tubular member, the support including:
• a projection longitudinally overlapping at least a portion of the cut section;
• and
• a low section longitudinally offset from the projection,
• the projection extending further in the first thickness direction than the low section and the first surface.
