PROBLEM TO BE SOLVED: To provide an image forming device capable of obtaining a stable image, without reducing the density of image and eliminating the need of periodically cleaning the surface of a toner mark sensor, by reducing the scattering of toner so as to hardly soil the surface of the toner mark sensor. SOLUTION: The image forming device is provided with a stirring part 80 for carrying developer, a developing roller 51 provided to be adjacent to the stirring part 80 and a photoreceptor drum 41C. The toner mark sensor 10 for detecting the density of a toner mark formed on the surface of the drum 41C is arranged in a position (a) corresponding to the downstream side in the carrying direction of the developer of the stirring part 80. |
