ABSTRACT:
An image forming apparatus having a photosensitive drum and a developing roller for coating a developer on the photosensitive drum. The image forming apparatus includes a plurality of light scanning units. Each of the light scanning units scans a light on the photosensitive drum to sharingly form an electrostatic latent image thereon. A selective input unit is provided to select between a normal mode and a saving mode. A controller controls, in the saving mode, a relatively less number of the light scanning units to scan the light on the photosensitive drum, as compared with in the normal mode. Thus, the developer can be saved in a simple and effective way.
