Belt offset correction device, fixing device, and image forming apparatus

A belt offset correction device comprising:

• an endless belt;
• a pressure roller that presses an outer side of the endless belt;
• an opposing member that is disposed inside the endless belt and sandwiches the endless belt with the pressure roller;
• a pair of pressure members that are disposed at both ends of the pressure roller to rotatably support the pressure roller and press the pressure roller against the opposing member;
• and
• a moving member that moves one pressure member of the pair of pressure members in a direction intersecting a pressing direction of the pressure roller,
• wherein each of the pair of pressure members comprises a fulcrum engaging section to be engaged with a rotation fulcrum at one end while being locked to a biasing member at a side opposite to the fulcrum engaging section,
• wherein at least one of the pressure roller and the opposing member comprises an elastic layer,
• wherein the moving member controls an offset of the endless belt by moving the one pressure member in a state where deformation of the elastic layer is regulated,
• wherein each of the pair of pressure members comprises a movement restrictor, and the deformation of the elastic layer is regulated by bringing the movement restrictor into contact with a stopper disposed at a predetermined position away from the rotation fulcrum,
• wherein an outer circumference of the opposing member comprises a cylindrical shape, and
• the moving member moves by forming an arc along the outer circumference of the opposing member on one end of the pressure roller.
