A control apparatus for a vibration type motor includes a processor or circuit that serves as a driving signal generating unit configured to generate a driving signal of the vibration type motor; and a booster circuit configured to boost the driving signal. The driving signal generating unit changes a duty ratio of the driving signal based on a driving frequency of the vibration type motor or a current flowing through the vibration type motor.
