Abstract
In a method for forming a digital image with use of electrophotographic process wherein the gradation is expressed by changing the laser intensity according to image information, at least one of the surface electric potential V.sub.O of photoconductor and the development bias electric voltage V.sub.B is controlled, and the laser intensity is controlled for gradation correction to compensate a change in gradation due to the control of V.sub.O and V.sub.B.
