PROBLEM TO BE SOLVED: To prevent toner from scattering, and to surely perform recovery of the waste toner derived from discharge. SOLUTION: This image forming device 1 is, provided with the image carrier 5, the image write-in part 4 for writing an electrostatic latent image on the image carrier 5 based on the image signal, a developing device 10 for developing the image while feeding the toner on the image carrier 5, and a transfer part for transferring the toner image on the image carrier 5, and moreover equipped with the toner density detecting means A for detecting the density of toner image in a developing device 10, an inside pattern image data production part B producing the inside pattern image for discharging the toner and the toner discharge processing part C composed so as to discharge the toner inside the developing device 10 by the inside pattern image formed according to the density of the toner image. |
