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 including an irradiated area and a not-irradiated area in a mixed manner, the electrostatic latent image forming method comprising:
adjusting an exposure condition of the irradiated area; and irradiating the image carrier with light under the adjusted exposure condition, wherein, in the pattern, the not-irradiated area includes a white dot and the irradiated area includes black dots, and wherein the adjusting includes adjusting an exposure condition of at least a first black dot that is adjacent to the white dot so that an exposure-amount for exposing the first black dot is larger than a predetermined exposure-amount for exposing a second black dot that is not adjacent to the white dot, and an exposure-time for exposing the first black dot is shorter than a predetermined exposure-time for exposing the second black dot. |
