Abstract:
An image forming apparatus which performs an exposure of a plurality of line images concurrently, by scanning an image carrier with a plurality of light beams in a main scanning direction and simultaneously drives the image carrier in a sub scanning direction, the image forming apparatus having: a plurality of light sources which are driven to emit the plurality of light beams corresponding to image data; a polygon mirror configured to deflect the plurality of light beams emitted from the plurality of light sources in a main scanning direction; and a control section which determines an image formation speed and switches, based on the determined image formation speed, a control between a control of changing a number of light sources used for light emission drive and a control of changing a number of polygon mirror use-surfaces used for a scanning with the light beams in the main scanning direction.
