ABSTRACT:
An image forming apparatus wherein the pulse width of an information signal for forming an information beam to be projected onto a photosensitive member is different depending on the image density of the image to be formed. An image density information of a latent image or a displayed image formed with the use of the information beam modulated in a reference signal is detected. In response to the result of the detection, the pulse width or the level of the information signal is controlled.
