Abstract
Certain embodiments provide a fuser including a cylindrical fixing belt, a heating unit configured to heat the fixing belt, a pressurized section, a first nip forming section, a second nip forming section, and a moving mechanism. The pressurized section is arranged in contact with the fixing belt. The first nip forming section is fixed in a position where the first nip forming section presses the fixing belt against the pressurized section. The second nip forming section is configured to be movable between a position where the second nip forming section can press the fixing belt against the pressurized section and a position where the second nip forming section is separated from the fixing belt. The moving mechanism moves the second nip forming section.
