PROBLEM TO BE SOLVED: To make it possible to form an image having a high picture quality.SOLUTION: A method for formation of an electrostatic latent image corresponding an image pattern including an image part 701 and a non-image part by exposing an image carrier with light according to the image pattern, in which the image part 701 is configured from plural pixels, a pixel group, which is smaller than a beam size of light, among pixel groups which are present on a border between pixels constituting the image part 701 and the non-image part is not exposed as a non-exposure pixel group 741, and a pixel group, which is present on a border with the non-exposure pixel group 741, among the pixels constituting the image part 701 is exposed as a high output exposure pixel group 743 at a light output value in which a predetermined light output value required for exposing said pixel group is added to a light output value required for exposing a non-exposure pixel group 743.SELECTED DRAWING: Figure 34 |
