An image formation apparatus includes an imaging light source, a photosensitive body and a correction light source. The imaging light source outputs light modulated in accordance with image data representing an image. An electrostatic latent image is formed at the photosensitive body by the light output from the imaging light source. The correction light source is provided separately from the imaging light source, and outputs light toward the photosensitive body for correcting one of variations in potential on the photosensitive body and irregularities in density distribution of an image, which image is to be formed in accordance with the electrostatic latent image that is formed on the photosensitive body by the imaging light source.

An image forming apparatus, forming an image by two-dimensionally fast and slow-scanning and exposing with light that has been modulated in accordance with image data representing an image and visualizing an electrostatic latent image with toner, includes a calculating unit that divides an image region in a fast-scanning direction into plural regions and calculates image data amounts to be used for image formation in the image data per each of the plural regions, and a correcting unit that corrects, on the basis of the calculation result of the calculating unit, unevenness of density in the fast-scanning direction in the toner image resulting from a distance between a position where the toner is supplied to a developing roll and a position where the toner is supplied to each of the plural regions.
摘要:
An image forming apparatus for continuously printing plural images has an empirical calibration part that performs color calibration processing based on a test image printed on recording paper, a predictive calibration part that performs color calibration processing based on a reference value that has been determined in advance, and a controller that allows the empirical calibration part and the predictive calibration part to perform color calibration processing. In the case where recording paper is switched and plural images are printed, the controller allows the empirical calibration part to perform color calibration processing when predetermined type of recording paper is used, and allows the predictive calibration part to perform color calibration processing when recording paper of other type is used.
