ABSTRACT:
A method for determining toner adhesion amounts of plural color toners on a photoreceptor. The method includes the steps of: (1) forming plural reference latent images, each of which is corresponding to a respective component color image of a reference toner image; (2) developing the reference latent images, each of which is developed with a respective color toner of the plural color toners, so that developed reference latent images are superimposed, each at a time, on the photoreceptor to form the reference toner image; (3) detecting the toner adhesion amounts of the plural color toners by detecting the reference toner image every time when one of the developed reference latent images is superimposed on the same portion of the photoreceptor; and (4) determining whether the toner adhesion amounts of the plural color toners are normal or abnormal according to results of the detecting step.
