Abstract
A light emitting elements drive control device includes: a supplying unit that supplies a common power source voltage to a plurality of light emitting elements whose light emission quantities are controlled individually by current controls; a determining unit that determines voltage ranges capable of assuring proper current control operations on the individual light emitting elements based on drive voltages for the respective light emitting elements that vary as the current controls are performed; and a setting unit that sets the power source voltage to be supplied from the supplying unit from a common voltage range of the voltage ranges determined by the determining unit.
