Abstract
An optical scanning apparatus includes a first rotating polygonal mirror that deflects a light beam such that the light beam scans a surface of a first image carrier, and a second rotating polygonal mirror that deflects a light beam such that the light beam scans a surface of a second image carrier. The optical scanning apparatus further includes a first phase control unit that performs phase control of the first rotating polygonal mirror based on a first detection signal output from a first detection unit and a first target phase, and a second phase control unit that performs phase control of the second rotating polygonal mirror based on a second detection signal output from a second detection unit and a second target phase, which is set with respect to the first target phase.
