Claim:
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 the laser light moves on the surface of the photosensitive member at a non-constant scanning velocity in a main scanning direction to form a latent image on the surface of the photosensitive member; a first correcting unit configured to correct an emission period of the laser light so that the emission period of the laser light becomes shorter as the scanning velocity increases, and/or the emission period of the laser light becomes longer as the scanning velocity decreases; and a second correcting unit configured to select at least one of correcting an emission ratio of the laser light so that the emission ratio of the laser light increases as the scanning velocity increases, and/or the emission ratio of the laser light decreases as the scanning velocity decreases, and correcting 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.
