Abstract
A motor that rotates a rotation shaft of a polygon mirror is mounted on a motor board. A first photoelectric conversion element senses beam light reflected by each of a plurality of mirror surfaces. A sensing target portion is provided to the rotation shaft. A light sensor is disposed apart from the motor board and includes a light emitting portion and a second photoelectric conversion element. An amplification circuit amplifies a sense signal of the second photoelectric conversion element. A control device controls a timing of starting to form an electrostatic latent image on the basis of a sense signal of the first photoelectric conversion element. The control device identifies a scanning surface that is scanning the beam light on the basis of the sense signal of the second photoelectric conversion element amplified by the amplification circuit, and adjusts a pixel pitch of the electrostatic latent image.
