Abstract
An image forming method which comprises copying an original on a photosensitive material employing a direct reversal photographic emulsion is disclosed. The method comprises conducting ordinary exposure when the original image is a positive image and conducting exposure at high illuminance when the original image is a negative image. Thereby, it is possible to obtain a direct positive image from either the original positive or original negative image. The process is greatly advantageous with respect to forming positive images since the process can be utilized to obtain positive images regardless whether the original image is positive or negative.
