Abstract:
1. An image forming apparatus comprising an optical scanning apparatus and a correction unit, the optical scanning apparatus including: a light source including a plurality of light emitting elements each configured to output, based on input image data, a light beam for irradiation of a photosensitive member driven to rotate, wherein the plurality of light emitting elements are arranged so that the photosensitive member is irradiated at different positions in a rotational direction with a plurality of the light beams output from the plurality of light emitting elements, the correction unit being configured to correct a scanning width of at least one of the plurality of light beams emitted from the plurality of light emitting elements based on the input image data, based on a result of the detection by the temperature detecting unit, so that the plurality of light beams output from the plurality of light emitting elements based on the input image data have the same scanning width in a scanning direction in which the plurality of light beams scan on the photosensitive member.
