Abstract:
An image forming apparatus in which an exposure is conducted by scanning of a laser beam, said apparatus comprising:(a) a photoreceptor for carrying a latent image thereon;(b) exposure means having a rotary polygonal mirror for exposing said photoreceptor to form the latent image thereon, wherein the laser beam is deflected and scanned onto said photoreceptor by rotating the rotary polygonal mirror;(c) control means for controlling a linear speed of said photoreceptor; and(d) braking means for decreasing forcibly a speed of rotation of the polygonal mirror,wherein when said control means decreases the linear speed of said photoreceptor according to an image formation mode, said braking means decreases the speed of rotation of the polygonal mirror.
