Abstract
The scanning apparatus and the image forming apparatus include a semiconductor laser emitting laser light for forming an electrostatic latent image according to image data on a photosensitive drum, a rotary polygon mirror scanning the laser light emitted from the semiconductor laser by rotation, a horizontal synchronization sensor arranged in a non-image area, and outputting a signal in response to the laser light being emitted, and a CPU performing intermittent emission control that causes the semiconductor laser to be emitted in an area in which the laser light is emitted to the horizontal synchronization sensor based on a BD cycle, the CPU switches the intermittent emission control based on the BD signal by a time the rotary polygon mirror reaches a target rotation speed.
