An oscillator device includes an oscillation system having first and second oscillators and first and second resilient supporting members, wherein the oscillation system has at least two frequencies of natural oscillation mode around a torsion axis which include a first resonance frequency f1 and a second resonance frequency f2, wherein there is a relationship that f2 is approximately two-fold of f1, and wherein a drive control member supplies, to a driving member, a driving signal which is comprised of a driving signal based on synthesizing a first driving signal having a first driving frequency and a second driving signal having a second driving frequency, and which is such driving signal that, among the first and second driving frequencies, a lower-frequency side driving frequency Df1 and a higher-frequency side driving frequency Df2 satisfy a relationship Df1×2=Df2 and that Df2 satisfies a relationship f2−|Δf/2|
