摘要 |
An electrostatic latent image forming method for forming, on an image carrier, an electrostatic latent image that has a pattern where there are an irradiated area and a not-irradiated area in a mixed manner, the electrostatic latent image forming method comprises; adjusting an exposure condition of an irradiated area that is included in the irradiated area and is adjacent to the not-irradiated area so that an electric field intensity of an electrostatic latent image that corresponds to the not-irradiated area is increased so as to prevent adhesion of a developer, and irradiating the image carrier with light under the adjusted exposure condition. |

1. An electrostatic latent image forming method for forming, on an image carrier, an electrostatic latent image that has a pattern where there are an irradiated area and a not-irradiated area in a mixed manner, the electrostatic latent image forming method comprising: adjusting an exposure condition of an irradiated area that is included in the irradiated area and is adjacent to the not-irradiated area so that an electric field intensity of an electrostatic latent image that corresponds to the not-irradiated area is increased so as to prevent adhesion of a developer; and irradiating the image carrier with light under the adjusted exposure condition wherein, in the pattern, the not-irradiated area is a white dot and the irradiated area is a black dot, and the adjusting includes adjusting an exposure condition of the black dot that is adjacent to the white dot in accordance with a number of black dots that are adjacent to the white dot. |
