Abstract
A semiconductor laser driving apparatus for driving a semiconductor laser serving as a light source for optical scanning, the semiconductor laser driving apparatus includes: first and second switching elements that are each capable of switching energization of the semiconductor laser ON/OFF; a first pulse generation unit that intermittently outputs first driving pulses to the first switching element in a first time slot; and a second pulse generation unit that outputs a second driving pulse to the second switching element in a second time slot different from the first time slot.
