ABSTRACT:
An object of the present invention is to prevent deterioration of measurement accuracy due to a substrate density change, by forming a density measurement image used for density measurement in a non-printing region of which substrate density change is smaller than that of a printing region. In order to achieve this object, there is provided, in an image formation apparatus for forming an image on an image support body in an electrophotographic system, an image processing apparatus. The apparatus forms the density measurement image in the non-printing region on the image support body, measures the density measurement image and controls an image formation condition of the image formation apparatus on the basis of a measurement of the density measurement image.
