Abstract
An image forming apparatus includes a density-measuring unit that has a substantially circular measurement field and that measures a density of a to-be-measured image for density measurement, which is moving in a moving direction, and a density-control unit that controls a density of an image and includes a to-be-measured image forming unit that forms the to-be-measured image having a shape following an outline of a density-measurement area defined by a path of the measurement field during a measurement rather than a substantially rectangular shape extending in the moving direction and including a front end of the to-be-measured image in the moving direction, the shape being within the substantially rectangular shape, a density-measuring section that causes the density-measuring unit to measure a density of the to-be-measured image, and a gradation-correction unit that performs gradation correction on the image by using the density of the to-be-measured image measured by the density-measuring section.
