ABSTRACT:
The present invention, for example, forms a test pattern image on the surface of a photosensitive member at predetermined periodicity and detects the density of said test pattern image. If the detected density value of the test pattern image is other than said target value, the charging voltage is preferentially adjusted to maintain a stable toner density. When the adjusted charging voltage attains either an upper limit or a lower limit, the toner density is adjusted.
