Abstract
An image recording apparatus which uses one type of photo-sensitive material to transfer an image from a original having a different density scale. The original image is given a primary exposure to the photo-sensitive material and the photo-sensitive material is given a direct exposure as an auxiliary exposure. After a certain amount of auxiliary exposure has been performed, the ratio of the amount of auxiliary exposure with respect to the amount of the total exposure of the part on the photo-sensitive material corresponding to the high density part of the original, is small, but because the ratio with respect to the amount of the total exposure of the part on the photo-sensitive material corresponding to the low density part of the original is large, the apparent .gamma.-characteristics of the photo-sensitive material is lowered, and a favorable image corresponding to the gradation of the original can be obtained.
