<p><P>PROBLEM TO BE SOLVED: To provide a long-life developing device 16 capable of preventing a toner supply part 58 from being excessively filled with toner, causing neither deterioration of toner nor sorting of particle size and further coping with miniaturization. <P>SOLUTION: The developing device 16 has a photoreceptor drum 11, a developing roller 53, a supply roller 54, a regulating member 55 and a stirring member 56. A first partition 61 is provided to partition the developing device 16 so as to form the toner supply part 58 in which the developing roller 53, the supply roller 54 and the regulating member 55 are arranged, and a toner storage part 59 in which the stirring member 56 is arranged, and a second partition 62 is provided nearer to the toner storage part 59 side than the first partition 61 so as to be opposed to the first partition 61. The first partition 61 has one or a plurality of apertures 63 at a position where it is opposed to the second partition 62, and a path part 64 where the toner moves is formed by the first partition 61 and the second partition 62. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
