Patent ID: 8320781

Claim:
An image processing apparatus, comprising: a determination unit adapted to determine a detection scheme of an amount of toner adhesion of a toner image based on attribute information of the toner image; a decision unit adapted to decide a pattern of the toner image according to the results of determination by the determination unit; a formation unit adapted to form the toner image with the pattern decided by the decision unit; and a measurement unit adapted to measure the amount of toner adhesion of the toner image by the determined detection scheme, for the toner image pattern formed by the formation unit unit, wherein the determination unit is adapted to determine, based on the attribute information of the toner image, as a detection scheme of the amount of toner adhesion of the toner image, whether to detect the amount of toner adhesion from a reflection position of reflected light from the toner image, or to detect the amount of toner adhesion from the amount of reflected light reflected from the toner image.
