ABSTRACT:
An apparatus such as a digital printer for forming a image with use of electrophotographic process with a reversal development system, the density is controlled automatically by varying the sensitizing electric potential V.sub.O of the photoconductor and the bias electric voltage V.sub.B of the development unit according to the detected density of the standard toner pattern, while gradation correction fog elimination and/or color balance can be performed at the same time automatically or manually by adjusting V.sub.O and V.sub.B.
