Image forming apparatus

In an image forming apparatus comprising an exposure light source, a printer head provided with a micro-shutter array which is disposed in the exposure light path from said exposure light source and comprises a plurality of micro-shutters each controlling the transmission or interruption of light therethrough, and an image bearing member so disposed to be irradiated with the light signal transmitted through the printer head;

• the improvement wherein
• said plurality of micro-shutters of said microshutter array are arranged in a matrix comprising a plurality of rows and a plurality of columns;
• each of said micro-shutters comprises a first electrode connected to a terminal of a thin film transistor, a second electrode which serves as a common electrode and a liquid crystal interposed between said first and second electrodes;
• and
• said first electrode is further provided with a conductor film in opposed relationship through an intermediate insulating film, said first electrode, intermediate insulating film and conductor film forming in combination a charge storage capacitor.
