发明名称 Electrostatic latent image forming method, electrostatic latent image forming apparatus, and image forming apparatus
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.

主权项 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.
