Abstract
An image forming apparatus includes a signal generating unit that stores information on a plurality of dither matrices preset in correspondence with the density level of toner to be attached to the photosensitive member and converts input image data based on the dither matrices to generate a driving signal. The signal generating unit stores information on a first dither matrix corresponding to a first density level and a second dither matrix corresponding to a second density level higher than the first density level. The first dither matrix includes a minute exposure area in which the exposure device is caused to emit light to attain a potential at which no toner adheres to the photosensitive member, and the second dither matrix includes a normal exposure area in which the exposure device is caused to emit light to attain a potential at which toner adheres to the photosensitive member.
