Abstract: An image forming apparatus includes a subjected-to-development member; a first developer-transporting unit; a regulator that regulates the thickness of a developer; a second developer-transporting unit; a density detecting unit that detects center density and edge density of a developed image formed on the subjected-to-development member by the first developer-transporting unit and the second developer-transporting unit; a reference-image forming controller that forms a reference developed image on the subjected-to-development member by forming an electrostatic latent image having a uniform image density at a center position and an edge position; and a speed controller that increases rotation speed of the second developer-transporting unit as compared to the case of forming the reference developed image if the center density of the reference developed image detected by the density detecting unit is lower than the edge density.
