    • An image forming apparatus forms an image by exposing an image bearer on the basis of image data including at least one predetermined pattern. The image forming apparatus includes a processing device that sets an exposure amount of a plurality of exposure pixels. The predetermined pattern is constituted by the plurality of exposure pixels, and a peripheral region of the predetermined pattern in the image data is constituted by a plurality of non-exposure pixels. The processing device sets an exposure amount of an exposure pixel in a specific region that is adjacent to a boundary between the predetermined pattern and the peripheral region and is constituted by at least one exposure pixel in the predetermined pattern, and an exposure amount of an exposure pixel in a region other than the specific region in the predetermined pattern to values different from each other.
    • 图像形成装置通过基于包括至少一个预定图案的图像数据曝光图像承载来形成图像。 图像形成装置包括设置多个曝光像素的曝光量的处理装置。 预定图案由多个曝光像素构成,图像数据中的预定图案的外围区域由多个非曝光像素构成。 处理装置设置与预定图案和周边区域之间的边界相邻的特定区域中的曝光像素的曝光量,并且由预定图案中的至少一个曝光像素构成曝光量,曝光量 像素在预定图案中的特定区域以外的区域中彼此不同。

    • An image forming method exposes a surface of an image bearer with light according to an image pattern including an image portion to form an electrostatic latent image, and includes: setting, among pixels constituting the image portion, at least a group of pixels existing at a boundary with respect to a non-image portion as a non-exposure pixel group, and at least a group of pixels existing at a boundary with respect to the non-exposure pixel group as a high power exposure pixel group; specifying, among the pixels constituting the image portion, a predetermined pixel as a target pixel, and a group of pixels existing at a boundary with respect to the non-image portion close to the target pixel as a boundary pixel group; and specifying a light power value of the target pixel based on image identification information acquired from the pixels constituting the image portion.
    • 图像形成方法根据包括图像部分的图像图案,用光曝光图像载体的表面以形成静电潜像,并且包括:在构成图像部分的像素中至少设置存在于 相对于作为非曝光像素组的非图像部分的边界,以及存在于相对于非曝光像素组的边界处的至少一组像素作为高曝光像素组; 在构成图像部分的像素中,将作为目标像素的预定像素和存在于靠近目标像素的非图像部分的边界处存在的像素组作为边界像素组; 以及基于从构成图像部分的像素获取的图像识别信息来指定目标像素的光功率值。
