Abstract: An image forming apparatus includes: a driving source configured to generate power; a first rotator configured to be drivingly rotated by the power generated by the driving source; a first power transmission system configured to transmit the power from the driving source to the first rotator; a second rotator configured to be drivingly rotated by the power generated by the driving source; and a second power transmission system configured to transmit the power to the second rotator from the first power transmission system. A damper having a torsion spring constant and a torsion viscous damping constant making a maximum positional change value of the first rotator equal to or smaller than a predetermined positional change value is disposed between the first power transmission system and the second power transmission system.

Abstract: A fixing device includes a heating rotating body driven by a motor, a pressing member, a biasing unit, a switching unit that receives rotational power of the motor in order to either separate the pressing member and the heating rotating body or to allow the biasing unit to press the pressing member and the heating rotating body together, a power transmission mechanism that transmits the rotational power of the motor to the switching unit over a first path or a second path, the first path having a larger reduction ratio, and a power transmission targeting unit that switches the target of transmission of rotational power of the motor between the heating rotating body and the switching unit depending on the rotational direction of the motor and that includes a path selection unit that selects the first path during separation and the second path during pressing by the switching unit.
