Abstract
An image forming apparatus includes a light scan head having a plurality of LED elements disposed along a main-scanning direction of a photoreceptor drum and configured to expose the photoreceptor drum with light, a developing device disposed to face the photoreceptor drum in the main-scanning direction and including a development roller configured to supply a developer to the photoreceptor drum, and a non-uniform density correction unit configured to control an intensity of light emitted from the plurality of LED elements of the light scan head based on correction data that corresponds to a tendency pattern of an expected non-uniform image density so as to correct the non-uniform density of an image that is to be formed on a recording medium.
