An image forming machine in which an image is formed on a recording material by an imagewise exposure to a light source that is modulated in accordance with to an image signal. The machine includes a device for generating a reference wave with a predetermined frequency, a generator for generating a pulse width modulating signal to modulate the light source in accordance with the image signal and the reference wave. A ratio of the frequency of the image signal to the predetermined frequency of the reference wave is set based on a relationship 1:(1+n/m) where n and m are positive integers and n is less than m.
