Abstract
An image forming apparatus including: a light source configured to emit a light beam based on an image signal; a deflector configured to deflect the light beam so that the light beam emitted from the light source is scanned on a surface of a photosensitive member in a main scanning direction; a storage portion configured to store a first magnification of an image with respect to a scanning position in the main scanning direction; and a controller configured to generate a second magnification of the image with respect to a reference color image, wherein the controller generates a third magnification based on the first magnification corrected based on the second magnification and the second magnification to correct the image signal based on the third magnification.

An image forming apparatus, comprising:
- a light source configured to emit a light beam based on an image signal;
- a deflector configured to deflect the light beam so that the light beam emitted from the light source is scanned on a surface of a photosensitive member in a main scanning direction;
- a storage portion configured to store a first magnification of an image with respect to a scanning position in the main scanning direction;
- and
- a controller configured to generate a second magnification of the image with respect to a reference color image,
- wherein the controller generates a third magnification based on the first magnification corrected based on the second magnification and the second magnification to correct the image signal based on the third magnification.

- a storage portion configured to store a first magnification of an image with respect to a scanning position in the main scanning direction;
- and
- a controller configured to generate a second magnification of the image with respect to a reference color image,
- wherein the controller generates a third magnification based on the first magnification and the second magnification to correct the image signal based on a difference between a first timing at which the image signal is corrected based on the first magnification and a second timing at which the image signal is corrected based on the third magnification.
