Moving device and image forming apparatus incorporating the moving device

A moving device comprising:

• at least one cam;
• a pressure roller configured to be moved by the at least one cam;
• at least one lever adjacent to a rotary shaft of the pressure roller and opposite a fixing roller;
• a biasing body configured to apply a biasing force to bias the pressure roller toward the at least one cam by pulling the at least one lever against the rotary shaft of the pressure roller;
• a drive source configured to apply a driving force to the at least one cam to press the at least one lever in a direction opposite the biasing force to reduce pressure between the pressure roller and the fixing roller;
• and
• a drive transmission device configured to transmit the driving force to the at least one cam, the drive transmission device including a load applying body configured to apply a load to a rotation of the at least one cam;
• wherein the load applying body is configured to apply the load to the rotation of the at least one cam in response to the biasing force of the biasing body acting on a direction of rotation of the at least one cam;
• wherein the load applying body is a torque limiter;
• wherein the drive transmission device includes a drive side coupling configured to receive the driving force from the drive source and a driven side coupling configured to engage with the drive side coupling;
• wherein the torque limiter is coupled with the drive side coupling and the driven side coupling;
• wherein the driving side coupling, the driven side coupling, and the torque limiter are attached to a drive shaft;
• wherein the drive side coupling and an end portion of the torque limiter on a drive side coupling side of the torque limiter are attached to the drive shaft so as to rotate integrally with the drive shaft;
• and
• wherein the end portion of the torque limiter on a driven side coupling side of the torque limiter is configured to rotate integrally with the driven side coupling.
