Abstract
Driver ICs are formed from low-temperature polycrystal silicon directly on an insulating sheet of a recording electrode body by forming a thin film of amorphous silicon, polycrystallizing the amorphous silicon by using excimer laser, and converting the polycrystallized silicon into a semiconductor circuit. Therefore, the step of mounting driver ICs on the insulating sheet is obviated. It becomes possible to produce a recording head and an image forming apparatus having a high resolution and a high reliability.
