Abstract

An optical scanning device, a driving method of an optical scanning device, and an image drawing system that can constantly maintain a frequency ratio between a frequency of a first driving signal and a frequency of a second driving signal in a case of changing the frequency of the first driving signal and the frequency of the second driving signal are provided. A driving controller provides a first driving signal having a first driving frequency corresponding to a first set value to a first actuator, provides a second driving signal having a second driving frequency corresponding to a second set value to a second actuator, changes the first driving frequency by changing the first set value in units of a first number obtained by dividing the first set value by a greatest common divisor of the first set value and the second set value, and changes the second driving frequency by changing the second set value in units of a second number obtained by dividing the second set value by the greatest common divisor.
