Dot image forming apparatus having controlled dot adhesion

摘要

In an image forming machine in which a latent image is formed on an image carrier using an exposure device corresponding to an image forming signal, and a toner image is formed by a developing device using toners, there is provided with a first adjustment device by which an adhesion amount of toner is adjusted, a discriminator by which an isolated dot or an edge dot is discriminated, a second adjustment device by which an adhesion amount of toner is adjusted according to a discrimination result by the discriminator, and a controller by which the adjustment conditions of the adhesion amount of the second adjustment device differ corresponding to the discriminated isolation dot or edge dot, and areas other than the discriminated dots.
