摘要：
An image forming machine, such as a printer or a copying machine for forming a toner image on a photoreceptor includes an image writer, such as a laser beam generator, for forming a latent image on the photoreceptor; a developer for developing the latent image with a developer, which includes a toner and a carrier; a controller for controlling a toner concentration of the developer so that the toner concentration is equalized; a circuit to automatically form a reference toner image on the photoreceptor; a detector for detecting a toner deposition amount of the reference toner image; and a controller circuit for decreasing a toner charge amount of the toner when the toner concentration is equalized and the toner deposition amount of the reference toner image is smaller than a predetermined value.
