Abstract: An image forming apparatus includes a dot forming unit responsive to a drive signal for forming a dot on a pixel when the drive signal is indicative of forming the dot to reproduce a halftone image. The apparatus further includes a drive signal generation circuit for generating the drive signal according to a video density signal, a deletion signal, an addition signal, and a directional signal. The deletion signal indicates that the video density signal of the pixel shows a shadow level and there is a first edge adjacent to the pixel in a first image around the pixel. The addition signal indicates that the video density signal of the pixel shows a highlight level and there is a second edge adjacent to the pixel in a second image around while the pixel, the directional signal indicates a direction of the first and second edges from the pixel. The drive signal is pulse-modulated by the video density signal.
