Abstract:
1. An image forming apparatus, comprising: an image carrier; an exposure unit configured to emit light for exposure onto the image carrier; a determination unit configured to determine, based on image data, a low density area in which a density of an image that is formed in accordance with the image data is lower than a predetermined density; and a control unit configured to control a pulse-width of a driving signal so as to cause the exposure unit to emit light, and to control a light emitting intensity of light emitted from the exposure unit that is driven by the driving signal, based on the image data, wherein the control unit controls the pulse-width of the driving signal for forming a pixel of interest included in a predetermined number of neighboring pixels in the low density area determined by the determination unit, based on image data corresponding to the predetermined number of neighboring pixels in the low density area, controls a light emitting intensity for the pixel of interest to be equal or more than a predetermined intensity, and controls light emitting intensities for pixels other than the pixel of interest to be less than the predetermined intensity.
