<p><P>PROBLEM TO BE SOLVED: To provide a developing device the developability of which is not lowered, even in high-speed development processing, and which can achieve miniaturization of an image forming apparatus. <P>SOLUTION: The developing device 141 includes: a first roller 9 which is arranged to be opposed to a photoreceptor drum 135, and which supplies toner to an electrostatic latent image formed on the photoreceptor drum 135; a second roller 11 which has a larger diameter than the first roller 9, and which is arranged to be opposed to the photoreceptor drum 135 above the first roller 9 and on a downstream side of the first roller 9 in the rotating direction R4 of the photoreceptor drum 135, and which supplies the toner to the electrostatic latent image formed on the photoreceptor drum 135; and a third roller 13 which is arranged to be opposed to the first and second rollers 9 and 11 below the photoreceptor drum 135, and which supplies the toner to the first and second rollers 9 and 11. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
