Claim Text:
1. An image-forming apparatus comprising: a light-irradiation unit configured to irradiate a surface of a charged photosensitive member with laser light emitted by a light source in accordance with image data so that a spot of the laser light on the surface of the photosensitive member moves at a non-constant scanning velocity in a main scanning direction to form a latent image on the surface of the photosensitive member; an image data correcting unit configured to correct a length in the main scanning direction of the image data by inserting one or more image data pieces into the image data, the number of the image data pieces increasing as the scanning velocity decreases, and/or extracting one or more image data pieces from the image data, the number of the image data pieces increasing as the scanning velocity increases; and a brightness correcting unit configured to correct a brightness of the laser light so that an emission brightness of the light source increases as the scanning velocity increases and/or the emission brightness of the light source decreases as the scanning velocity decreases, wherein the image-forming apparatus forms a toner image by applying toner onto the latent image.
