Image forming apparatus and optical scanning apparatus for scanning photosensitive member with light spot
An image forming apparatus includes: a scanning unit configured to form a latent image on a photosensitive member, wherein a scanning speed changes within a scan line; a control unit configured to perform correction control of a luminance and a light-emitting time of a light source; a holding unit configured to hold profile information indicating a change of the light spot due to an environment or due to a position of the pixel. The holding unit is further configured to hold scanning information indicating the light-emitting time of the light source or the luminance of the light source with respect to a pixel, for correcting a change in the scanning time of the pixel, and the control unit is further configured to perform the correction control based on the scanning information and the profile information.
