In an image processing apparatus for forming a visible image by developing an electrostatic latent image formed on an image carrier, transferring the visible image onto an intermediate transfer body, and then transferring the visible image onto a recording medium, a density sensor detects a patch formed on the intermediate transfer body, and corrects the measurement timing of the density sensor on the basis of the detected position of the patch. The density sensor then detects the density of a toner image for density correction to execute density control. With this control, density control can be done after any mechanical error between the intermediate transfer body and density sensor is corrected, thus improving the density control precision.
