Abstract:
An image forming apparatus, comprising:a photosensitive member; a light source for emitting onto said photosensitive member a light beam modulated in accordance with a digital image signal, the digital image signal representing a selectable one of bi-level and multi-level image data; developing means for developing an electrostatic image formed on said photosensitive member by exposure of said photosensitive member to the modulated light beam; multi-level image adjusting means for adjusting the image by changing a &ggr; conversion characteristic when the digital image signal represents multi-level image data; and bi-level image adjusting means for adjusting the image by changing a development condition when the digital image signal represents bi-level image data, wherein, when the digital image signal represents multi-level image data, the &ggr; conversion characteristic is changed and the development condition is unchanged when forming the image; and wherein, when the digital image signal represents bi-level image data, the development condition is changed and the &ggr; conversion characteristic is unchanged when forming the image.
