Abstract
According to one embodiment, an image forming apparatus includes a rotatable photoconductor, a laser light source configured to output a laser beam according to an image, a polygon mirror positioned to reflect the laser beam while rotating and cause the laser beam to be incident on the photoconductor along a main scanning direction to form an electrostatic latent image, a photodetector configured to detect the laser beam reflected by the polygon mirror, a developer, a transfer mechanism, and a processor. The processor (a) controls the laser light source such that a light emission intensity of the laser light source is constant when the laser beam is incident on the photodetector, regardless of a rotation speed of the polygon mirror and (b) controls the output timing of the laser beam based on a detection result of the photodetector.
