Abstract:
A light scanning apparatus comprising:a rotating reflector having at least one reflecting surface rotated around a rotation axis, said rotating reflector reflecting and deflecting an incident light beam by said at least one reflecting surface; andcontrol means for controlling a stopping position of said rotating reflector so that said rotating reflector stops rotating in a state in which one reflecting surface of said at least one reflecting surface faces a certain direction, said control means comprising:a first magnetic body disposed inside said rotating reflector and rotated integrally with said rotating reflector; anda second magnetic body provided on a locus of rotation of said first magnetic body and in a state of non-contact with said rotating reflector, said second magnetic body and said first magnetic body generating attraction therebetween at least when said rotating reflector stops rotating,wherein said light scanning apparatus scans an exposure surface of a recording medium by the light beam reflected from said at least one reflecting surface of said rotating reflector.
