Abstract
A light deflector for use in a laser printer, for example, is composed of a motor having a drive shaft and a light reflecting member such as a rotating multiple-surface mirror or a hologram. The motor is subjected to magnetic field ripples the number of which is equal to a multiple by an integer of the number of light reflecting surfaces of the light reflecting member.
