Abstract
An image forming apparatus includes: an output section that forms an electrostatic latent image onto an image carrier by using light emitted by a light source and outputs an image onto a recording medium by developing the formed electrostatic latent image; a memory that stores a sinusoidal set value representing a correction amount for correcting periodic density variations that occur in an image, which is to be formed, in a subscanning direction and that are caused by a rotating body, and a correction table in which correction amounts for correcting density variations that occur in an image, which is to be formed, in the subscanning direction and that are not caused by a rotating body are each stored in association with a corresponding position in the subscanning direction; and a processor configured to: calculate a first correction amount corresponding to a rotation phase of a rotating body included in the output section on a basis of the sinusoidal set value and retrieve a second correction amount corresponding to a position in the subscanning direction from the correction table when an image is formed in the output section; and perform, by using the calculated first correction amount and the retrieved second correction amount, correction of a density of an image that is formed onto a recording medium.
