Abstract
Optical scanning device includes as follows. Light emitting element emits light beam in First direction and Second direction. Mirror unit reflects light beam emitted in First direction. First light receiving element receives light beam reflected by Mirror unit. Reference signal generator generates BD signal based on signal output from First light receiving element. Second light receiving element receives light beam emitted in Second direction. Light quantity controller measures signal output from Second light receiving element and automatically controls the light quantity of light beam emitted during APC period. Light quantity controller starts the automatic control at a timing at which light beam reflected by Mirror unit passes through the position of Second light receiving element and is received by First light receiving element and completes the automatic control before light beam reflected by Mirror unit reaches the position of Second light receiving element next.
