A processing apparatus includes a first structure supported by a vibration reduction mechanism, a drive mechanism supported by the first structure and configured to drive an object to be processed, a second structure supported by the first structure and facing the object, an actuator configured to apply a force to the first structure, a sensor configured to detect a vibration of the second structure, and a controller configured to feedforward-control the actuator based on feedforward control information so as to reduce vibrations of the first structure and the second structure. The feedforward control information includes first control information determined in advance based on an output from the sensor.
