Abstract
An image forming apparatus according to one embodiment includes an image carrier that moves in a first direction, a developing device, a detector, and a determination unit. The developing device uses a developer on the surface of the image carrier to forma strip-shaped image inclined with respect to the width direction perpendicular to the moving direction of the image carrier. The detector detects the density difference occurring in the strip-shaped image formed on the surface of the image carrier while moving in the width direction. The determination unit determines based on a detection result by the detector whether or not there is an abnormality.
