Abstract:
An image forming apparatus in which a multi-potential latent image is formed on a charged photosensitive material by a light scan of light scanning means, a visible image is formed by depositing a developing agent onto said multi-potential latent image, and said visible image is transferred to a transfer material and is outputted,wherein said light scanning means has exposure amount modulating means for modulating an exposure amount in accordance with pixel density information and expressing an image dark/light state for pixels on said photosensitive material divided into a predetermined size, andsaid exposure amount modulating means divides an image density region to a highlight density region, a halftone density region, or a dark density region, modulates the density data of a predetermined number of pixels which are continuous in a light scanning direction by the density data of several pixels among said pixels in said highlight density region, and doesn't record the remaining pixels.
