<p>PURPOSE: To provide a charge generator used for an electrostatic image forming device, which is provided with an electron emission member excellent in film quality and whose reproduced image quality is drastically improved. CONSTITUTION: This charge generator is constituted by one-dimensionally or two-dimensionally arranging a charge generating control element 100 constituted of a picture element switching transistor 101 formed on a semiconductor substrate 103, a layer insulating film 110 formed on the upper part of the transistor 101, a picture element electrode 111 formed on the film 110 and connected to one end of the transistor 101, the electron emission member 112 formed on the electrode 111, and an upper electrode 113 formed on the member 112 and provided with an electron emission hole 114.</p> |
