Abstract
An image forming apparatus includes a photoconductor drum, an exposure device, a development device, and a controller. The exposure device irradiates the photoconductor drum with a light beam and thereby forms an electrostatic latent image. The development device causes toner to adhere to the electrostatic latent image and thereby generates a toner image. The controller controls the exposure device. Further the exposure device includes a polygon mirror, a polygon motor, a mark detector, and an actuator. The polygon mirror is configured to scan the light beam. The polygon motor is configured to rotate the polygon mirror. The mark detector is configured to detect a mark attached to a motor axis of the polygon motor. The actuator is configured to be enabled to move the mark detector. Furthermore, the controller moves the mark detector to a position corresponding to an operation condition of the exposure device using the actuator.
