| 发明名称 | Image forming method of exposing the surface of an image carrier with light and image forming apparatus | ||
| 摘要 | An image forming method includes: exposing a surface of an image carrier with a light based on an image pattern including an image portion and a non-image portion to form an electrostatic latent image corresponding to the image pattern. The image portion is made up of a plurality of pixels. Some of the pixels that make up the image portion are exposed with light of a first output value that is higher than a prescribed optical output value when the entire pixels corresponding to the image portion are exposed over a prescribed time period. | ||

| 主权项 | 1. An image forming method comprising: exposing a surface of an image carrier with a light based on an image pattern including an image portion and a non-image portion to form an electrostatic latent image corresponding to the image pattern, wherein the image portion is made up of a plurality of pixels, some of the pixels that make up the image portion are exposed with light of a first optical output value that is higher than a prescribed optical output value when the entire pixels corresponding to the image portion are exposed over a prescribed time period, and wherein an integrated amount of light on the pixels exposed with light of the first optical output value is equal to an integrated amount of light of the optical output value when the entire pixels corresponding to the image portion is exposed with light of the prescribed optical output value over a prescribed time period. | ||
