Abstract
In an image forming apparatus including a pulse-width modulating unit for subjecting an image-density signal to pulse-width modulation and an image-forming unit for forming an image in accordance with a pulse-width modulation signal outputted by the pulse-width modulating unit, an arrangement is provided such that the image is formed with a small number of lines when the image density is a low density, while the image is formed with a large number of lines when the image density is a medium/high density. In an example of the arrangement thereof, the pulse-width modulating unit has a unit for effecting modulation on the basis of a plurality of different modulation periods, and is provided with a selecting unit for selecting a modulation period of a pulse-width modulated wave to be outputted, in accordance with the image-density signal.
