Abstract
An image to be formed on paper () is held on the surface of photo-sensitive drum (). This is a latent image of static electricity formed by an LED exposer (). Then, the developing roller () puts toner on the surface of photo sensitive drum (), so as to develop a toner image. Meanwhile, the toner conveying roller () supplies toner to the developing roller (). In this occasion, the printer controller () calculates the image density of image data () with dot counter (). And, it decides the first voltage impressed to developing roller () by developing bias source () as well as the second voltage impressed to toner conveying roller () by stretching bias source () according to the image density of original image.
