<p>PROBLEM TO BE SOLVED: To form a bright image that is superior in sharpness of an image such as an ability for reproducing fine lines, for example, even when a normal developing is carried out. SOLUTION: In this image forming device, a photoreceptor drum 18 with aγcharacteristic is more than 1.5, where an avalanche phenomenon is generated, is used and after a surface of the photoreceptor drum is uniformly electrified to be positive by a scorotron type electrifying device 20, a part to which toner is not stuck on the photoreceptor drum 18 is exposed by a laser beam from a scanner unit 10 based on a prescribed image data, an electrostatic latent image is formed by this unexposed part and the toner that is negatively electrified is fed to this electrostatic latent image from a rotary developing unit 19.</p> |
