ABSTRACT:
An image forming apparatus comprising an exposure light source, a printer head which comprises a group of micro-shutters each controlling the transmission or interruption of light from the exposure light source, and an image bearing so disposed to be irradiated with light signals transmitted through the printer head. The group of micro-shutters are arranged in a matrix comprising a plurality of rows and a plurality of columns. The group of micro-shutters are formed by a substrate having thereon a plurality of segment electrodes each forming a shutter and connected to a drain of a thin film transistor, another substrate having thereon a common electrode, and a liquid crystal interposed between the substrates. The image forming apparatus further comprises means for applying a scanning signal to the gate of the thin film transistor and applying an electric signal corresponding to image information in synchronism with the scanning signal.
