Abstract
An image forming apparatus includes: a photoconductor drum; an optical scanning device that drives a light source to scan a surface of the photoconductor drum and form a latent image on the surface; a developing device that develops the latent image; and a density detector to detect density variation of an image in a rotation direction of the photoconductor drum, the image being developed by the developing device. The optical scanning device includes a processing device that is capable of correcting a driving signal for driving the light source on a basis of an output signal of the density detector to adjust at least either one of a correction period and a correction strength of correction data for the driving signal for a rotation period of the photoconductor drum.
