    摘要: A toner adhesion amount information detection unit detects toner adhesion amount information. An image density unevenness detection unit detects image density unevenness in an image. A toner image forming unit forms a latent image on the surface of the latent image bearer, and performs the developing processing by applying developing bias between the latent image bearer and a developer bearer. The toner adhesion amount information detection unit detects, as the toner adhesion amount information, developing current flowing between the developer bearer and the latent image bearer. The image density unevenness detection unit obtains, from the image information, an index value indicating a toner adhesion amount of a toner image portion when the developing current is detected, and detects the image density unevenness based on the image information and the developing current when the index value indicates a toner adhesion amount of a prescribed amount or more.
