Image forming apparatus and image forming method for reducing toner bearing amount, and storage medium thereof

摘要

An image forming apparatus that can reduce a toner bearing amount stably regardless of a density of an image. The image forming apparatus comprises a first generating unit which generates a reference pattern, and a second generating unit which generates, based on image data, a correction pattern for thinning out dots at a region from halftone density to high density. The image data is converted based on the reference pattern generated by the first generating unit and the correction pattern generated by the second generating unit. The image forming apparatus further comprises a photoreceptor. The photoreceptor is charged, the charged photoreceptor is exposed based on the converted image data to form an electrostatic latent image, and the electrostatic latent image is developed.

1. An image forming apparatus comprising:
a first generating unit configured to generate a reference pattern; a second generating unit configured to generate, based on image data, a correction pattern for thinning out dots at a region from halftone density to high density; a converting unit configured to convert the image data based on the reference pattern generated by the first generating unit and the correction pattern generated by the second generating unit; a photoreceptor; a charging unit configured to charge the photoreceptor; an exposure unit configured to expose the charged photoreceptor based on the image data converted by the converting unit, to form an electrostatic latent image; and a developing unit configured to develop the electrostatic latent image.
